+&lt;p&gt;&lt;strong&gt;Versions Affected:&lt;/strong&gt;
+5.0.0 to 8.3.1&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+The affected versions are vulnerable to a Remote Code Execution through the
+VelocityResponseWriter.  A Velocity template can be provided through
+Velocity templates in a configset &lt;code&gt;velocity/&lt;/code&gt; directory or as a parameter.
+A user defined configset could contain renderable, potentially malicious,
+templates.  Parameter provided templates are disabled by default, but can
+be enabled by setting &lt;code&gt;params.resource.loader.enabled&lt;/code&gt; by defining a
+response writer with that setting set to &lt;code&gt;true&lt;/code&gt;.  Defining a response
+writer requires configuration API access.&lt;/p&gt;
+&lt;p&gt;Solr 8.4 removed the params resource loader entirely, and only enables the
+configset-provided template rendering when the configset is &lt;code&gt;trusted&lt;/code&gt; (has
+been uploaded by an authenticated user).&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;br&gt;
+Ensure your network settings are configured so that only trusted traffic
+communicates with Solr, especially to the configuration APIs.&lt;/p&gt;

+&lt;p&gt;&lt;strong&gt;Versions Affected:&lt;/strong&gt;&lt;br&gt;
+Solr 8.1.1 and 8.2.0 for Linux&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+The 8.1.1 and 8.2.0 releases of Apache Solr contain an
+insecure setting for the ENABLE_REMOTE_JMX_OPTS configuration option
+in the default solr.in.sh configuration file shipping with Solr.&lt;/p&gt;
+&lt;p&gt;Windows users are not affected.&lt;/p&gt;
+&lt;p&gt;If you use the default solr.in.sh file from the affected releases, then
+JMX monitoring will be enabled and exposed on RMI_PORT (default=18983),
+without any authentication. If this port is opened for inbound traffic
+in your firewall, then anyone with network access to your Solr nodes
+will be able to access JMX, which may in turn allow them to upload
+malicious code for execution on the Solr server.&lt;/p&gt;
+&lt;p&gt;The vulnerability is already public [1] and mitigation steps were
+announced on project mailing lists and news page [3] on August 14th,
+without mentioning RCE at that time.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;br&gt;
+Make sure your effective solr.in.sh file has ENABLE_REMOTE_JMX_OPTS set
+to 'false' on every Solr node and then restart Solr. Note that the
+effective solr.in.sh file may reside in /etc/defaults/ or another
+location depending on the install. You can then validate that the
+'com.sun.management.jmxremote*' family of properties are not listed in
+the "Java Properties" section of the Solr Admin UI, or configured in a
+secure way.&lt;/p&gt;
+&lt;p&gt;There is no need to upgrade or update any code.&lt;/p&gt;
+&lt;p&gt;Remember to follow the Solr Documentation's advice to never expose Solr
+nodes directly in a hostile network environment.&lt;/p&gt;

+Solr versions prior to 5.0.0 are vulnerable to an XML resource
+consumption attack (a.k.a. Lol Bomb) via it’s update handler. By leveraging
+XML DOCTYPE and ENTITY type elements, the attacker can create a pattern
+that will expand when the server parses the XML causing OOMs&lt;/p&gt;

+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+The DataImportHandler, an optional but popular module to pull in data from
+databases and other sources, has a feature in which the whole DIH
+configuration can come from a request's "dataConfig" parameter. The debug
+mode of the DIH admin screen uses this to allow convenient debugging /
+development of a DIH config. Since a DIH config can contain scripts, this
+parameter is a security risk. Starting with version 8.2.0 of Solr, use of
+this parameter requires setting the Java System property
+&lt;code&gt;enable.dih.dataConfigParam&lt;/code&gt; to true.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;  &lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;Upgrade to 8.2.0 or later, which is secure by default.&lt;/li&gt;
+&lt;li&gt;or, edit solrconfig.xml to configure all DataImportHandler usages with an "invariants" section listing the "dataConfig" parameter set to am empty string.&lt;/li&gt;
+&lt;li&gt;Ensure your network settings are configured so that only trusted traffic communicates with Solr, especially to the DIH request handler.  This is a best practice to all of Solr.&lt;/li&gt;

+&lt;li&gt;Handling of incorrect or absent values was improved for many request parameters. In such cases the response is 400 http code (Bad Request), instead of 500 (Internal Server Error) as it was before.&lt;/li&gt;
+&lt;li&gt;Breaching timeAllowed limit correctly responded as 200 http code (Ok) with partialResults=true, instead of 500 (Internal Server Error) as it was before in SolrCloud. Note, it was fixed for essential request parameters, if you still evidence 500 caused by timeAllowed, please submit an issue with log excerpt attached.&lt;/li&gt;
+&lt;li&gt;In-place updates work for collections created with route.field.&lt;/li&gt;
+&lt;li&gt;Asynchronous Collection API calls do not return completion status prematurely when more than one replica reside per note.&lt;/li&gt;
+&lt;li&gt;Range Facets and Terms Component performance has been optimized for certain cases.&lt;/li&gt;

+&lt;h4 id="query-execution"&gt;Query execution&lt;/h4&gt;
+&lt;p&gt;Term queries, phrase queries and boolean queries introduced new optimization that enables efficient skipping over non-competitive documents when the total hit count is not needed. Depending on the exact query and data distribution, queries might run between a few percents slower and many times faster, especially term queries and pure disjunctions.&lt;/p&gt;
+&lt;p&gt;In order to support this enhancement, some API changes have been made:
+ * &lt;code&gt;TopDocs.totalHits&lt;/code&gt; is no longer a long but an object that gives a lower bound of the actual hit count.
+ * &lt;code&gt;IndexSearcher&lt;/code&gt;'s &lt;code&gt;search&lt;/code&gt; and &lt;code&gt;searchAfter&lt;/code&gt; methods now only compute total hit counts accurately up to 1,000 in order to enable this optimization by default.
+ * Queries are now required to produce non-negative scores.&lt;/p&gt;
+&lt;h4 id="codecs"&gt;Codecs&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Postings now index score impacts alongside skip data. This is how term queries optimize collection of top hits when hit counts are not needed.&lt;/li&gt;
+&lt;li&gt;Doc values introduced jump tables, so that advancing runs in constant time. This is especially helpful on sparse fields.&lt;/li&gt;
+&lt;li&gt;The terms index &lt;code&gt;FST&lt;/code&gt; is now loaded off-heap for non-primary-key fields using &lt;code&gt;MMapDirectory&lt;/code&gt;, reducing heap usage for such fields.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="custom-scoring"&gt;Custom scoring&lt;/h4&gt;
+&lt;p&gt;The new &lt;code&gt;FeatureField&lt;/code&gt; allows efficient integration of static features such as a pagerank into the score. Furthermore, the new &lt;code&gt;LongPoint#newDistanceFeatureQuery&lt;/code&gt; and &lt;code&gt;LatLonPoint#newDistanceFeatureQuery&lt;/code&gt; methods allow boosting by recency and geo-distance respectively.

+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Solr now uses HTTP/2 for inter-node communication to attain greater efficiency.
+Details:  Solr is switching from Apache HttpClient to Jetty Client for adding HTTP/2 support.
+Most frequent inter-communication between nodes like indexing and query are now sent in HTTP/2.
+HTTP/1.1 practically allows only one outstanding request per TCP connection this means that for sending multiple requests at the same time multiple TCP connections must be established.
+This leads to waste of resources on both-sides and long GC-pause.
+Solr 8 with HTTP/2 support overcomes that problem by allowing multiple requests can be sent in parallel using a same TCP connection.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Nested documents (AKA child documents or block join) is significantly improved.
+Most improvements come from storing and leveraging more information about the relationships in the index, like the named relationship between a child and its parent.
+This information is used by the [child] doc transformer to return children in nested form instead of flat.
+There is plenty more that can be done with this in the future.
+Another key improvement is that nested documents can be deleted or replaced in a natural way without orphaning child documents; although care is still needed with delete-by-query.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;

+&lt;code&gt;&amp;amp;dataConfig=&amp;lt;inlinexml&amp;gt;&lt;/code&gt; parameter of Solr's DataImportHandler. It can be
+used as XXE using file/ftp/http protocols in order to read arbitrary local
+files from the Solr server or the internal network. See [1] for more details.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;br&gt;
+Users are advised to upgrade to either Solr 6.6.3 or Solr 7.3.0 releases both
+of which address the vulnerability. Once upgrade is complete, no other steps
+are required. Those releases disable external entities in anonymous XML files
+passed through this request parameter. &lt;/p&gt;
+&lt;p&gt;If users are unable to upgrade to Solr 6.6.3 or Solr 7.3.0 then they are
+advised to disable data import handler in their solrconfig.xml file and
+restart their Solr instances. Alternatively, if Solr instances are only used
+locally without access to public internet, the vulnerability cannot be used
+directly, so it may not be required to update, and instead reverse proxies or
+Solr client applications should be guarded to not allow end users to inject
+&lt;code&gt;dataConfig&lt;/code&gt; request parameters. Please refer to [2] on how to correctly
+secure Solr servers.&lt;/p&gt;

+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+Apache Solr uses Apache Tika for parsing binary file types such as
+doc, xls, pdf etc. Apache Tika wraps the jmatio parser
+(https://github.com/gradusnikov/jmatio) to handle MATLAB files. The
+parser uses native deserialization on serialized Java objects embedded
+in MATLAB files. A malicious user could inject arbitrary code into a
+MATLAB file that would be executed when the object is deserialized.&lt;/p&gt;
+&lt;p&gt;This vulnerability was originally described at
+http://mail-archives.apache.org/mod_mbox/tika-user/201611.mbox/%3C2125912914.1308916.1478787314903%40mail.yahoo.com%3E&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;br&gt;
+Users are advised to upgrade to either Solr 5.5.5 or Solr 6.6.2 or Solr 7.1.0
+releases which have fixed this vulnerability.&lt;/p&gt;
+&lt;p&gt;Solr 5.5.5 upgrades the jmatio parser to v1.2 and disables the Java
+deserialisation support to protect against this vulnerability.&lt;/p&gt;
+&lt;p&gt;Solr 6.6.2 and Solr 7.1.0 have upgraded the bundled Tika to v1.16.&lt;/p&gt;
+&lt;p&gt;Once upgrade is complete, no other steps are required.&lt;/p&gt;

+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Critical security fix: Fix for a 0-day exploit (CVE-2017-12629), details: https://s.apache.org/FJDl. RunExecutableListener has been disabled by default (can be enabled by -Dsolr.enableRunExecutableListener=true) and resolving external entities in the XML query parser (defType=xmlparser or {!xmlparser ... }) is disabled by default.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Fix for a bug where Solr was attempting to load the same core twice (Error message: "Lock held by this virtual machine").&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;

+&lt;/ul&gt;
+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+The details of this vulnerability were reported on public mailing
+lists. See https://s.apache.org/FJDl&lt;/p&gt;
+&lt;p&gt;The first vulnerability relates to XML external entity expansion in
+the XML Query Parser which is available, by default, for any query
+request with parameters deftype=xmlparser. This can be exploited to
+upload malicious data to the /upload request handler. It can also be
+used as Blind XXE using ftp wrapper in order to read arbitrary local
+files from the solr server.&lt;/p&gt;
+&lt;p&gt;The second vulnerability relates to remote code execution using the
+RunExecutableListener available on all affected versions of Solr.&lt;/p&gt;
+&lt;p&gt;At the time of the above report, this was a 0-day vulnerability with a
+working exploit affecting the versions of Solr mentioned in the
+previous section. However, mitigation steps were announced to protect
+Solr users the same day. See
+https://lucene.apache.org/solr/news.html#12-october-2017-please-secure-your-apache-solr-servers-since-a-zero-day-exploit-has-been-reported-on-a-public-mailing-list&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;br&gt;
+Users are advised to upgrade to either Solr 6.6.2 or Solr 7.1.0
+releases both of which address the two vulnerabilities. Once upgrade is
+complete, no other steps are required.&lt;/p&gt;
+&lt;p&gt;If users are unable to upgrade to Solr 6.6.2 or Solr 7.1.0 then they
+are advised to restart their Solr instances with the system parameter
+&lt;code&gt;-Ddisable.configEdit=true&lt;/code&gt;. This will disallow any changes to be made
+to your configurations via the Config API. This is a key factor in
+this vulnerability, since it allows GET requests to add the
+RunExecutableListener to your config. Users are also advised to re-map
+the XML Query Parser to another parser to mitigate the XXE
+vulnerability. For example, adding the following to the solrconfig.xml
+file re-maps the xmlparser to the edismax parser:
+&lt;code&gt;&amp;lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&amp;gt;&lt;/code&gt;&lt;/p&gt;

+will reference in future communication about resolution and mitigation
+steps.&lt;/p&gt;
+&lt;p&gt;Here is what we're recommending and what we're doing now:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Until fixes are available, all Solr users are advised to restart their
+Solr instances with the system parameter &lt;code&gt;-Ddisable.configEdit=true&lt;/code&gt;.
+This will disallow any changes to be made to configurations via the
+Config API. This is a key factor in this vulnerability, since it allows
+GET requests to add the RunExecutableListener to the config. This is
+sufficient to protect you from this type of attack, but means you cannot
+use the edit capabilities of the Config API until the other fixes
+described below are in place. Users are also advised to remap
+the XML Query Parser to another parser to mitigate the XXE
+vulnerability. For example, adding the following to the solrconfig.xml
+file maps the &lt;code&gt;xmlparser&lt;/code&gt; to the &lt;code&gt;edismax&lt;/code&gt; parser:
+&lt;code&gt;&amp;lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&amp;gt;&lt;/code&gt;.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new release of Lucene/Solr was in the vote phase, but we have now
+pulled it back to be able to address these issues in the upcoming 7.1
+release. We will also determine mitigation steps for users on earlier
+versions, which may include a 6.6.2 release for users still on 6.x.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The RunExecutableListener will be removed in 7.1. It was previously
+used by Solr for index replication but has been replaced and is no
+longer needed.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The XML Parser will be fixed and the fixes will be included in the 7.1
+release.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+This has been assigned a public CVE (CVE-2017-12629) which we

+&lt;p&gt;Here is what we're recommending and what we're doing now:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Until fixes are …&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;</summary><content type="html">&lt;p&gt;Please secure your Solr servers since a zero-day exploit has been
+reported on a &lt;a href="https://s.apache.org/FJDl"&gt;public mailing list&lt;/a&gt;.
+This has been assigned a public CVE (CVE-2017-12629) which we
+will reference in future communication about resolution and mitigation
+steps.&lt;/p&gt;
+&lt;p&gt;Here is what we're recommending and what we're doing now:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Until fixes are available, all Solr users are advised to restart their
+Solr instances with the system property &lt;code&gt;-Ddisable.configEdit=true&lt;/code&gt;.
+This will disallow any changes to be made to configurations via the
+Config API. This is a key factor in this vulnerability, since it allows
+GET requests to add the RunExecutableListener to the config. This is
+sufficient to protect you from this type of attack, but means you cannot
+use the edit capabilities of the Config API until the other fixes
+described below are in place. Users are also advised to remap
+the XML Query Parser to another parser to mitigate the XXE
+vulnerability. For example, adding the following to the solrconfig.xml
+file maps the &lt;code&gt;xmlparser&lt;/code&gt; to the &lt;code&gt;edismax&lt;/code&gt; parser:
+&lt;code&gt;&amp;lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&amp;gt;&lt;/code&gt;.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new release of Lucene/Solr was in the vote phase, but we have now
+pulled it back to be able to address these issues in the upcoming 7.1
+release. We will also determine mitigation steps for users on earlier
+versions, which may include a 6.6.2 release for users still on 6.x.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The RunExecutableListener will be removed in 7.1. It was previously
+used by Solr for index replication but has been replaced and is no
+longer needed.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The XML Parser will be fixed and the fixes will be included in the 7.1
+release.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The 7.1 release was already slated to include a change to disable the
+&lt;code&gt;stream.body&lt;/code&gt; parameter by default, which will further help protect
+systems.&lt;/p&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Doc values switched from random access to iterators.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The 7.0 codec now sparsely encodes sparse doc values and length normalization factors ("norms"), which also translates to optimization in both indexing, and search on sparse values. With these changes, you finally only pay for what you actually use with doc values, in index size, indexing performance, etc.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index time boost for documents is now removed.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Substantial performance gains for delete and update heavy Lucene usage; see http://blog.mikemccandless.com/2017/07/lucene-gets-concurrent-deletes-and.html for details&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Query scoring is now simpler with removal of coord factor, and query normalization.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Classic query parser no longer splits on whitespaces. This enables better multi-word synonym support.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The version of Lucene that created the index segment would be recorded, along with the version that last modified the index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter, used to add, update and delete documents in your index, will no longer accept broken token offsets sometimes produced by mis-behaving token filters.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexReader exposes methods that are typically used to manage resources whose lifetime needs to mimic the lifetime of segments/indexes, typically caches. They have been made much less trappy.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The dimensional points API now takes a field name up front to offer per-field points access, matching how the doc values APIs work.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The PostingsHighlighter was removed. Migrating to the UnifiedHighlighter should be straight-forward.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-for-this-solr-release-include"&gt;Highlights for this Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Replica Types - Solr 7 supports different replica types, which handle updates differently. In addition to pure NRT operation where all replicas build an index and keep a replication log, you can now also add so called PULL replicas, achieving the read-speed optimized benefits of a master/slave setup while at the same time keeping index redundancy.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Auto-scaling. Solr can now allocate new replicas to nodes using a new auto scaling policy framework. This framework will in future releases enable Solr to move shards around based on load, disk etc.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Indented JSON is now the default response format for all APIs, pass wt=xml and/or indent=off to use the previous unindented XML format.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The JSON Facet API now supports two-phase facet refinement to ensure accurate counts and statistics for facet buckets returned in distributed mode.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Streaming Expressions adds a new statistical programming syntax for the statistical analysis of sql queries, random samples, time series and graph result sets.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Analytics Component version 2.0, which now supports distributed collections, expressions over multivalued fields, a new JSON request language, and more.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The new v2 API, exposed at /api/ and also supported via SolrJ, is now the preferred API, but /solr/ continues to work.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new '_default' configset is used if no config is specified at collection creation. The data-driven functionality of this configset indexes strings as analyzed text while at the same time copying to a '*_str' field suitable for faceting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Both Apache Lucene and Solr 7.0.0 were tested to be fully compatible with the release of Java 9 and its module system Jigsaw, coming out tomorrow on September 21st!&lt;/p&gt;

In addition to pure NRT operation where all replicas build an index and keep a replication log, you can now also add so called PULL replicas, achieving the read-speed optimized benefits of a master/slave setup while at the same time keeping index redundancy.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Auto-scaling. Solr can now allocate new replicas to nodes using a new auto scaling policy framework. This framework will in future releases enable Solr to move shards around based on load, disk etc.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Indented JSON is now the default response format for all APIs, pass wt=xml and/or indent=off to use the previous unindented XML format.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The JSON Facet API now supports two-phase facet refinement to ensure accurate counts and statistics for facet buckets returned in distributed mode.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Streaming Expressions adds a new statistical programming syntax for the statistical analysis of sql queries, random samples, time series and graph result sets.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Analytics Component version 2.0, which now supports distributed collections, expressions over multivalued fields, a new JSON request language, and more.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The new v2 API, exposed at /api/ and also supported via SolrJ, is now the preferred API, but /solr/ continues to work.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new '_default' configset is used if no config is specified at collection creation. The data-driven functionality of this configset indexes strings as analyzed text while at the same time copying to a '*_str' field suitable for faceting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr 7 is tested with and verified to support Java 9.&lt;/p&gt;
+&lt;/li&gt;

+&lt;p&gt;&lt;strong&gt;Description&lt;/strong&gt;:&lt;/p&gt;
+&lt;p&gt;Solr's Kerberos plugin can be configured to use delegation tokens, which allows an application to reuse the authentication of an end-user or another application.
+There are two issues with this functionality (when using SecurityAwareZkACLProvider type of ACL provider e.g. SaslZkACLProvider),&lt;/p&gt;
+&lt;p&gt;Firstly, access to the security configuration can be leaked to users other than the solr super user. Secondly, malicious users can exploit this leaked configuration for privilege escalation to further expose/modify private data and/or disrupt operations in the Solr cluster.&lt;/p&gt;
+&lt;p&gt;The vulnerability is fixed from Solr 6.6.1 onwards.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation&lt;/strong&gt;:&lt;br&gt;
+6.x users should upgrade to 6.6.1&lt;/p&gt;

+&lt;/ul&gt;
+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+Solr uses a PKI based mechanism to secure inter-node communication
+when security is enabled. It is possible to create a specially crafted
+node name that does not exist as part of the cluster and point it to a
+malicious node. This can trick the nodes in cluster to believe that
+the malicious node is a member of the cluster. So, if Solr users have
+enabled BasicAuth authentication mechanism using the BasicAuthPlugin
+or if the user has implemented a custom Authentication plugin, which
+does not implement either "HttpClientInterceptorPlugin" or
+"HttpClientBuilderPlugin", his/her servers are vulnerable to this
+attack. Users who only use SSL without basic authentication or those
+who use Kerberos are not affected.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation&lt;/strong&gt;:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;6.x users should upgrade to 6.6.0 or higher&lt;/li&gt;
+&lt;li&gt;5.x users should obtain the latest source from git and apply this patch:

+&lt;p&gt;&lt;strong&gt;Description:&lt;/strong&gt;&lt;br&gt;
+When using the Index Replication feature, Solr nodes can pull index files from
+a master/leader node using an HTTP API which accepts a file name. However,
+Solr did not validate the file name, hence it was possible to craft a special
+request involving path traversal, leaving any file readable to the Solr server
+process exposed. Solr servers protected and restricted by firewall rules
+and/or authentication would not be at risk since only trusted clients and users
+would gain direct HTTP access.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Mitigation:&lt;/strong&gt;&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;6.x users should upgrade to 6.4.1&lt;/li&gt;
+&lt;li&gt;5.x users should upgrade to 5.5.4&lt;/li&gt;
+&lt;li&gt;4.x, 3.x and 1.4 users should upgrade to a supported version of Solr or setup proper firewalling, or disable the ReplicationHandler if not in use.&lt;/li&gt;
+&lt;/ul&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene's best efforts to un-map memory mapped files with "MMapDirectory" now work with the latest Java9 early access builds&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new similarity "BooleanSimilarity" that gives terms a score that is equal to their query boost&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The axiomatic family of similarities (6 in total) based on https://www.eecis.udel.edu/~hfang/pubs/sigir05-axiom.pdf&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new token filter "SynonymGraphFilter" that outputs a correct graph structure for multi-token synonyms at query time&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Graph token streams, such as those produced by the "SynonymGraphFilter", are now handled accurately by query parsers&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new collector "DocValuesStatsCollector" gives the ability to compute statistics on DocValues field&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;It is now possible to filter "SortedDocValues" and "SortedSetDocValues" terms enum with a compiled automaton&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The "UnifiedHighlighter" can now highlight fields with queries that don't necessarily refer to that field&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;DrillSideways can now run queries concurrently&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index sorting now supports sorting on multi-valued fields using MIN, MAX, etc. selectors&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Points do not store the implicit split dimension in the 1-dimension case. This saves between 6% memory for the largest types such an InetAddressPoint to 33% for the smaller types such as HalfFloatPoint.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The BKD in-memory index for dimensional points now uses a compressed format, using substantially less RAM in some cases&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The BKD writing now buffers each leaf block in heap before writing to disk, giving a small speedup in points-heavy use cases&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;"TermAutomatonQuery" now rewrites to more efficient queries when possible&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;p&gt;Streaming:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Addition of a HavingStream to Streaming API and Streaming Expressions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Addition of a priority Streaming Expression&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Streaming expressions now support collection aliases&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Machine Learning:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;Configurable Learning-To-Rank (LTR) support: upload feature definitions, extract feature values, upload your own machine learnt models and use them to rerank search results.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Faceting:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Added "param" query type to facet domain filter specification to obtain filters via query parameters&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Any facet command can be filtered using a new parameter filter. Example:  { type:terms, field:category, filter:"user:yonik" }&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Scripts / Command line:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;A new command-line tool to manage the snapshots functionality&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;bin/solr and bin/solr.cmd now use mkroot command&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;SolrCloud / SolrJ&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;LukeResponse now supports dynamic fields&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solrj client now supports hierarchical clusters and other topics marker&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Collection backup/restore are extensible.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Security:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Support Secure Impersonation / Proxy User for Solr authentication&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Key Store type can be specified in solr.in.sh file for SSL&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New generic authentication plugins: 'HadoopAuthPlugin' and 'ConfigurableInternodeAuthHadoopPlugin' that delegate all functionality to Hadoop authentication framework&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Query / QueryParser / Highlighting:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;A new highlighter: The Unified Highlighter.  Try it via &lt;code&gt;hl.method=unified&lt;/code&gt;; many popular highlighting parameters / features are supported.  It's the highest performing highlighter, especially for large documents.  Highlighting phrase queries and exotic queries are supported equally as well as the Original Highlighter (aka the default/standard one).  Please use this new highlighter and report issues since it will likely become the default one day.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Leading wildcard in complexphrase query parser are now accepted and optimized with the &lt;code&gt;ReversedWildcardFilterFactory&lt;/code&gt; when it's provided&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Metrics:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Use metrics-jvm library to instrument jvm internals such as GC, memory usage and others.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A lot of metrics have been added to the collection: index merges, index store I/Os, query, update, core admin, core load thread pools, shard replication, tlog replay and replicas&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new /admin/metrics API to return all metrics collected by Solr via API.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Misc changes:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;The new config parameter 'maxRamMB'can now limit the memory consumed by the FastLRUCache&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new document processor 'SkipExistingDocumentsProcessor' that skips duplicate inserts and ignores updates to missing docs&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;FieldCache information fetched via the mbeans handler or seen via the UI now displays the total size used.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new config flag 'enable' allows to enable/disable any cache&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Please note, this release cannot be built from source with Java 8 update 121,
+use an earlier version instead! This is caused by a bug introduced into the
+Javadocs tool shipped with that update. The workaround was too late for this
+Lucene release. Of course, you can use the binary artifacts.&lt;/p&gt;

+&lt;li&gt;
+&lt;p&gt;A brand new "UnifiedHighlighter" derivative of the PostingsHighlighter that can consume offsets from postings, term vectors, or analysis. It can highlight phrases as accurately as the standard Highlighter. Light term vectors can be used with offsets in postings for fast wildcard (MultiTermQuery) highlighting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SimpleQueryParser now parses '*' to MatchAllDocsQuery&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;FuzzyQuery now matches all terms within the specified edit distance, even if they are short terms&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Points do not store the implicit split dimension in the 1-dimension case. This saves between 6% memory for the largest types such an InetAddressPoint to 33% for the smaller types such as HalfFloatPoint.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Many other changes and bug fixes&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;p&gt;DocValues, streaming, /export, machine learning&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Optimize, store and deploy AI models in Solr&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Ability to add custom streaming expressions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New streaming expressions such as "fetch", "executor", and "commit" added.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Parallel SQL accepts &amp;lt;, &amp;gt;, =, etc., symbols.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Support facet scoring with the scoreNodes expression&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Retrieving docValues as stored values was sped up by using the proper leaf reader rather than ask for a global view.  In extreme cases, this leads to a 100x speedup.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Faceting:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;facet.method=enum can bypass exact counts calculation with facet.exists=true, it just returns 1 for terms which exists in result docset&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add "overrequest" parameter to JSON Facet API to control amount of overrequest  on a distributed terms facet&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Logging:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;You can now set Solr's log level through environment variable SOLR_LOG_LEVEL&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;GC logs are rotated by JVM to a max of 9 files, and backed up via bin/solr scripts&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr's logging verbosity at the INFO level has been greatly reduced by moving much logging to DEBUG level&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The solr-8983-console.log file now only logs STDOUT and STDERR output, not all log4j logs as before&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr's main log file, solr.log, is now written to SOLR_LOGS_DIR without changing log4j.properties&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Start scripts:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Allow 180 seconds for shutdown before killing solr (configurable, old limit 5s) (Unix only)&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Start scripts now exits with informative message if using wrong Java version&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Fixed "bin/solr.cmd zk upconfig" command which was broken on windows&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;You can now ask for DEBUG logging simply with '-v' option, and for WARN logging with '-q' option&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;SolrCloud:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;The DELETEREPLICA API can accept a 'count' parameter and remove "count" number of replicas from each shard if the shard name is not provided&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The config API shows expanded useParams for request handlers inline&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Ability to create/delete/list snapshots at collection level&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The modify collection API now waits for the modified properties to show up in the cluster state before returning&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Many bug fixes related to SolrCloud recovery for data safety and faster recovery times.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Security:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;SolrJ now supports Kerberos delegation tokens&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Pooled SSL connections were not being re-used. This is now fixed.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Fix for the blockUnknown property which made inter-node communication impossible&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Support SOLR_AUTHENTICATION_OPTS and SOLR_AUTHENTICATION_CLIENT_CONFIGURER in windows bin/solr.cmd script&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New parameter -u &lt;user:pass&gt; in bin/post to pass basicauth credentials&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Misc changes:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Optimizations to lower memory allocations when indexing JSON as well as for replication between solr cloud nodes.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new Excel workbook (.xlsx) response writer has been added. Use 'wt=xlsx' request parameter on a query request to enable.&lt;/p&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;The CREATE_NEW flag is passed when creating a file to ensure Lucene is really write-once&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index numeric ranges (min and max value in a single field) and search by overlapping range&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter methods return a sequence number indicating effective order of operations across threads&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;UkrainianMorfologikAnalyzer is a new dictionary based analyzer for the Ukrainian language&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The Polygon class can now be created from a GeoJSON string&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Compound file creation now verifies checksum of its component files&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index time sorting is now a core feature, and supports dimensional points&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;StandardAnalyzer is moved to core and is the default analyzer&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MatchNoDocsQuery now includes the reason it was created&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;QueryParser can now be told to not pre-split on whitespace&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MMapDirectory tries harder to prevent SIGSEGV if buggy code tries to execute
+    searches after the index was closed, but it's still best effort&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MMapDirectory no longer allocates weak references to ease garbage collection&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Conjunction (MUST, FILTER) queries are faster&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Dimensional points have much faster (~40%) flush time and use less space in the index&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;p&gt;DocValues, streaming, /export, machine learning&lt;/p&gt;

+&lt;p&gt;DocValues can now be used with BoolFields&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Date and boolean support added to /export handler&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add "scoreNodes" streaming graph expression&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Support parallel ETL with the "topic" expression&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Feature selection and logistic regression on text via new streaming expressions: "features" and "train"&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;bin/solr script&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Add basic auth support to the bin/solr script&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;File operations to/from Zookeeper are now supported&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;SolrCloud&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;New tag 'role' in replica placement rules, e.g. rule=role:!overseer keeps new repicas off overseer nodes&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CDCR: fall back to whole-index replication when tlogs are insufficient&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New REPLACENODE command to decommission an existing node and replace it with another new node&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New DELETENODE command to delete all replicas on a node&lt;/p&gt;

+&lt;/ul&gt;
+&lt;p&gt;Security&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Add Kerberos delegation token support&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Support secure impersonation / proxy user for Kerberos authentication&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Misc changes&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;A large number of regressions were fixed in the new Admin UI&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New boolean comparison function queries comparing numeric arguments: gt, gte, lt, lte, eq&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Upgraded Extraction module to Apache Tika 1.13.&lt;/p&gt;

+&lt;p&gt;Java 8 is the minimum Java version required.&lt;/p&gt;
+&lt;/li&gt;

+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene classification module now works on Lucene Documents using a KNearestNeighborClassifier or SimpleNaiveBayesClassifier.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The spatial module no longer depends on third-party libraries. Previous spatial classes have been moved to a new spatial-extras module.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Spatial4j has been updated to a new 0.6 version hosted by locationtech.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;TermsQuery performance boost by a more aggressive default query caching policy.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexSearcher's default Similarity is now changed to BM25Similarity.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Easier method of defining custom CharTokenizer instances.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Improved defaults for "Similarity" used in Solr, in order to provide better default experience for new users.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Improved "Similarity" defaults for users upgrading: DefaultSimilarityFactory has been removed, implicit default Similarity has been changed to SchemaSimilarityFactory, and SchemaSimilarityFactory has been modified to use BM25Similarity as the default for field types that do not explicitly declare a Similarity.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Deprecated GET methods for schema are now accessible through the bulk API. The output has less details and is not backward compatible.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Users should set useDocValuesAsStored="false" to preserve sort order on multi-valued fields that have both stored="true" and docValues="true".&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Formatted date-times are more consistent with ISO-8601. BC dates are now better supported since they are now formatted with a leading '-'. AD years after 9999 have a leading '+'. Parse exceptions have been improved.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Deprecated SolrServer and subclasses have been removed, use SolrClient instead.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The deprecated &lt;nrtMode&gt; configuration in solrconfig.xml has been removed. Users must remove it from solrconfig.xml.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SolrClient.shutdown() has been removed, use SolrClient.close() instead.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The deprecated zkCredientialsProvider element in solrcloud section of solr.xml is now removed. Use the correct spelling (zkCredentialsProvider) instead.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added support for executing Parallel SQL queries across SolrCloud collections. Includes StreamExpression support and a new JDBC Driver for the SQL Interface.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New features and capabilities added to the streaming API.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added support for SELECT DISTINCT queries to the SQL interface.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New GraphQuery to enable graph traversal as a query operator.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New support for Cross Data Center Replication consisting of active/passive replication for separate SolrClouds hosted in separate data centers.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Filter support added to Real-time get.&lt;/p&gt;

+&lt;li&gt;
+&lt;p&gt;Column alias support added to the Parallel SQL Interface.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New command added to switch between non/secure mode in zookeeper.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Sandbox geo point queries have graduated into the spatial module, and now use a more efficient binary term encoding for smaller index size, faster indexing, and decreased search-time heap usage&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+&lt;p&gt;The PERSIST CoreAdmin action has been removed&lt;/p&gt;

+&lt;p&gt;Release Highlights:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;The schema version has been increased to 1.6, and Solr now returns non-stored doc values fields along with stored fields&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The PERSIST CoreAdmin action has been removed&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The mergePolicy element is deprecated in favor of a similar mergePolicyFactory element, in solrconfig.xml&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CheckIndex now works on HdfsDirectory&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;RuleBasedAuthorizationPlugin now allows wildcards in the role, and accepts an 'all' permission&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Users can now choose compression mode in SchemaCodecFactory&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr now supports Lucene's XMLQueryParser&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Collections APIs now have async support&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Uninverted field faceting is re-enabled, for higher performance on rarely changing indices&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Also available is the Solr Reference Guide for Solr 5.5. This PDF serves as the definitive user's manual for Solr 5.5.

+&lt;p&gt;The &lt;a href="https://github.com/apache/lucene-solr/"&gt;GitHub mirror&lt;/a&gt; remains at
+the same location as before, but the contents have changed. We now have
+one unified repo preserving the full history of both Lucene and Solr.
+If you had a GitHub fork, you will find
+that it has changed its "forked from" location, and any Pull Request will go to
+that other fork instead of to the Lucene developers. The only known solution is to
+delete your existing fork and re-fork from &lt;a href="https://github.com/apache/lucene-solr/"&gt;GitHub&lt;/a&gt;.&lt;/p&gt;
+&lt;p&gt;If you had active code changes and Pull Requests against our old GitHub mirror,

+&lt;li&gt;The Filter class is deprecated in favour of FILTER clauses in a BooleanQuery&lt;/li&gt;

+&lt;ul&gt;
+&lt;li&gt;PhraseQuery and BooleanQuery are now immutable&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="new-features"&gt;New features&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Added a new org.apache.lucene.search.join.CheckJoinIndex class that can be used to validate that an index has an appropriate structure to run join queries&lt;/li&gt;
+&lt;li&gt;Added a new BlendedTermQuery to blend statistics across several terms&lt;/li&gt;
+&lt;li&gt;New common suggest API that mirrors Lucene's Query/IndexSearcher APIs for Document based suggester.&lt;/li&gt;
+&lt;li&gt;IndexWriter can now be initialized from an already open near-real-time or non-NRT reader&lt;/li&gt;
+&lt;li&gt;Add experimental range tree doc values format and queries, based on a 1D version of the spatial BKD tree, for a faster and smaller alternative to postings-based numeric and binary term filtering.  Range trees can also handle values larger than 64 bits.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="geo-related-features-and-improvements"&gt;Geo-related features and improvements&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Added GeoPointField, GeoPointInBBoxQuery, GeoPointInPolygonQuery for simple "indexed lat/lon point in bbox/shape" searching&lt;/li&gt;
+&lt;li&gt;Added experimental BKD geospatial tree doc values format and queries, for fast "bbox/polygon contains lat/lon points"&lt;/li&gt;
+&lt;li&gt;Use doc values to post-filter GeoPointField hits that fall in boundary cells, resulting in smaller index, faster searches and less heap used for each query&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="optimizations"&gt;Optimizations&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Reduce RAM usage of FieldInfos, and speed up lookup by number, by using an array instead of TreeMap except in very sparse cases&lt;/li&gt;
+&lt;li&gt;Faster intersection of the terms dictionary with very finite automata, which can be generated eg. by simple regexp queries&lt;/li&gt;
+&lt;li&gt;Various bugfixes and optimizations since the 5.2.0 release.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;In addition to many other improvements in the security framework, Solr now includes an AuthenticationPlugin implementing HTTP Basic Auth that stores credentials securely in ZooKeeper. This is a simple way to require a username and password for anyone accessing Solr’s admin screen or APIs.&lt;/li&gt;
+&lt;li&gt;In built AuthorizationPlugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in ZooKeeper.&lt;/li&gt;
+&lt;li&gt;The JSON Facet API can now change the domain for facet commands, essentially doing a block join and moving from parents to children, or children to parents before calculating the facet data.&lt;/li&gt;
+&lt;li&gt;Major improvements in performance of the new Facet Module / JSON Facet API.&lt;/li&gt;
+&lt;li&gt;Query and Range Facets under Pivot Facets. Just like the JSON Facet API, pivot facets can how nest other facet types such as range and query facets.&lt;/li&gt;
+&lt;li&gt;More Like This Query Parser options. The MoreLikeThis QParser now supports all options provided by the MLT Handler. The query parser is much more versatile than the handler as it works in cloud mode as well as anywhere a normal query can be specified.&lt;/li&gt;
+&lt;li&gt;Added Schema API support in SolrJ&lt;/li&gt;
+&lt;li&gt;Added Scoring mode for query-time join and block join.&lt;/li&gt;
+&lt;li&gt;Added Smile response format&lt;/li&gt;

+&lt;li&gt;Added a new org.apache.lucene.search.join.CheckJoinIndex class that can be used to validate that an index has an appropriate structure to run join queries&lt;/li&gt;
+&lt;li&gt;Added a new BlendedTermQuery to blend statistics across several terms&lt;/li&gt;
+&lt;li&gt;New common suggest API that mirrors Lucene's Query/IndexSearcher APIs for Document based suggester.&lt;/li&gt;
+&lt;li&gt;IndexWriter can now be initialized from an already open near-real-time or non-NRT reader&lt;/li&gt;
+&lt;li&gt;Add experimental range tree doc values format and queries, based on a 1D version of the spatial BKD tree, for a faster and smaller alternative to postings-based numeric and binary term filtering.  Range trees can also handle values larger than 64 bits.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="geo-related-features-and-improvements"&gt;Geo-related features and improvements&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Added GeoPointField, GeoPointInBBoxQuery, GeoPointInPolygonQuery for simple "indexed lat/lon point in bbox/shape" searching&lt;/li&gt;
+&lt;li&gt;Added experimental BKD geospatial tree doc values format and queries, for fast "bbox/polygon contains lat/lon points"&lt;/li&gt;
+&lt;li&gt;Use doc values to post-filter GeoPointField hits that fall in boundary cells, resulting in smaller index, faster searches and less heap used for each query&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="optimizations"&gt;Optimizations&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Reduce RAM usage of FieldInfos, and speed up lookup by number, by using an array instead of TreeMap except in very sparse cases&lt;/li&gt;
+&lt;li&gt;Faster intersection of the terms dictionary with very finite automata, which can be generated eg. by simple regexp queries&lt;/li&gt;
+&lt;li&gt;Various bugfixes and optimizations since the 5.2.0 release.&lt;/li&gt;

+&lt;p&gt;Solr 5.3 Release Highlights:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;In addition to many other improvements in the security framework, Solr now includes an AuthenticationPlugin implementing HTTP Basic Auth that stores credentials securely in ZooKeeper. This is a simple way to require a username and password for anyone accessing Solr’s admin screen or APIs.&lt;/li&gt;
+&lt;li&gt;In built AuthorizationPlugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in ZooKeeper.&lt;/li&gt;
+&lt;li&gt;The JSON Facet API can now change the domain for facet commands, essentially doing a block join and moving from parents to children, or children to parents before calculating the facet data.&lt;/li&gt;
+&lt;li&gt;Major improvements in performance of the new Facet Module / JSON Facet API.&lt;/li&gt;
+&lt;li&gt;Query and Range Facets under Pivot Facets. Just like the JSON Facet API, pivot facets can how nest other facet types such as range and query facets.&lt;/li&gt;
+&lt;li&gt;More Like This Query Parser options. The MoreLikeThis QParser now supports all options provided by the MLT Handler. The query parser is much more versatile than the handler as it works in cloud mode as well as anywhere a normal query can be specified.&lt;/li&gt;
+&lt;li&gt;Added Schema API support in SolrJ&lt;/li&gt;
+&lt;li&gt;Added Scoring mode for query-time join and block join.&lt;/li&gt;
+&lt;li&gt;Added Smile response format&lt;/li&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Span queries now share document conjunction/intersection code with boolean queries, and use two-phased iterators for faster intersection by avoiding loading positions in certain cases.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added two-phase support to SpanNotQuery, and SpanPositionCheckQuery and its subclasses: SpanPositionRangeQuery, SpanPayloadCheckQuery, SpanNearPayloadCheckQuery, SpanFirstQuery.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a new query time join to the join module that uses global ordinals, which is faster for subsequent joins between reopens.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New CompositeSpatialStrategy combines speed of RPT with accuracy of SDV. Includes optimized Intersect predicate to avoid many geometry checks. Uses TwoPhaseIterator.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New LimitTokenOffsetFilter that limits tokens to those before a configured maximum start offset.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New spatial PackedQuadPrefixTree, a generally more efficient choice than QuadPrefixTree, especially for high precision shapes. When used, you should typically disable RPT's pruneLeafyBranches option.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Expressions now support bindings keys that look like zero arg functions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SpanWithinQuery and SpanContainingQuery that return spans inside of / containing another spans.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New Spatial "Geo3d" API with partial Spatial4j integration. It is a set of shapes implemented using 3D planar geometry for calculating spatial relations on the surface of a sphere. Shapes include Point, BBox, Circle, Path (buffered line string), and Polygon.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 5.1.0 release.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-this-solr-release-include"&gt;Highlights of this Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Restore API allows restoring a core from an index backup.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;JSON Facet API&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;unique() is now implemented for numeric and date fields&lt;/li&gt;
+&lt;li&gt;Optional flatter form via a "type" parameter&lt;/li&gt;
+&lt;li&gt;Added support for "mincount" parameter in range facets to suppress buckets less than that count&lt;/li&gt;
+&lt;li&gt;Multi-select faceting support for the Facet Module via the "excludeTags" parameter which disregards any matching tagged filters for that facet.&lt;/li&gt;
+&lt;li&gt;hll() facet function for distributed cardinality via HyperLogLog algorithm.
+See examples at http://yonik.com/solr-count-distinct/&lt;/li&gt;
+&lt;/ul&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new "facet.range.method" parameter to let users choose how to do range faceting between an implementation based on filters (previous algorithm, using "facet.range.method=filter") or DocValues ("facet.range.method=dv")&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Rule-based Replica assignment during collection, shard, and replica creation.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Stats component:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;New 'cardinality' option for stats.field, uses HyperLogLog to efficiently estimate the cardinality of a field w/bounded RAM. Blog post: https://lucidworks.com/blog/hyperloglog-field-value-cardinality-stats/&lt;/li&gt;
+&lt;li&gt;stats.field now supports individual local params for 'countDistinct' and 'distinctValues'. 'calcdistinct' is still supported as an alias for both options.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr security&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;Authentication and Authorization frameworks that define interfaces, and mechanisms to create, load, and use authorization/authentication plugins have been added.&lt;/li&gt;
+&lt;li&gt;A Kerberos authentication plugin which would allow running a Kerberized Solr setup.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr Streaming Expressions
+   See https://cwiki.apache.org/confluence/display/solr/Streaming+Expressions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;bin/post (and SimplePostTool in -Dauto=yes mode) now sends rather than skips files without a known content type, as "application/octet-stream", provided it still is in the allowed filetypes setting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HDFS transaction log replication factor is now configurable&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A cluster-wide property can now be be added/edited/deleted using the zkcli script and doesn't require a running Solr instance.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New spatial RptWithGeometrySpatialField, based on CompositeSpatialStrategy, which blends RPT indexes for speed with serialized geometry for accuracy.  Includes a Lucene segment based in-memory shape cache.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Refactored Admin UI using AngularJS. It isn't the default, but a parallel UI interface in this release.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr has internally been upgraded to use Jetty 9.&lt;/p&gt;

+&lt;p&gt;Stats component:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;New 'cardinality' option for stats.field, uses HyperLogLog to efficiently estimate the cardinality of a field w/bounded RAM. Blog post: https://lucidworks.com/blog/hyperloglog-field-value-cardinality-stats/&lt;/li&gt;
+&lt;li&gt;stats.field now supports individual local params for 'countDistinct' and 'distinctValues'. 'calcdistinct' is still supported as an alias for both options.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr security&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;Authentication and Authorization frameworks that define interfaces, and mechanisms to create, load, and use authorization/authentication plugins have been added.&lt;/li&gt;
+&lt;li&gt;A Kerberos authentication plugin which would allow running a Kerberized Solr setup.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr Streaming Expressions
+   See https://cwiki.apache.org/confluence/display/solr/Streaming+Expressions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;bin/post (and SimplePostTool in -Dauto=yes mode) now sends rather than skips files without a known content type, as "application/octet-stream", provided it still is in the allowed filetypes setting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HDFS transaction log replication factor is now configurable&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A cluster-wide property can now be be added/edited/deleted using the zkcli script and doesn't require a running Solr instance.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New spatial RptWithGeometrySpatialField, based on CompositeSpatialStrategy, which blends RPT indexes for speed with serialized geometry for accuracy.  Includes a Lucene segment based in-memory shape cache.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Refactored Admin UI using AngularJS. It isn't the default, but a parallel UI interface in this release.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Solr has internally been upgraded to use Jetty 9.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Solr 5.2.0 also includes many other new features as well as numerous
+optimizations and bugfixes of the corresponding Apache Lucene release.&lt;/p&gt;
+&lt;p&gt;Also available is the Solr Reference Guide for Solr 5.2. This 591 page

+&lt;p&gt;Lucene 5.2.0 release highlights:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Span queries now share document conjunction/intersection code with boolean queries, and use two-phased iterators for faster intersection by avoiding loading positions in certain cases.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added two-phase support to SpanNotQuery, and SpanPositionCheckQuery and its subclasses: SpanPositionRangeQuery, SpanPayloadCheckQuery, SpanNearPayloadCheckQuery, SpanFirstQuery.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a new query time join to the join module that uses global ordinals, which is faster for subsequent joins between reopens.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New CompositeSpatialStrategy combines speed of RPT with accuracy of SDV. Includes optimized Intersect predicate to avoid many geometry checks. Uses TwoPhaseIterator.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New LimitTokenOffsetFilter that limits tokens to those before a configured maximum start offset.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New spatial PackedQuadPrefixTree, a generally more efficient choice than QuadPrefixTree, especially for high precision shapes. When used, you should typically disable RPT's pruneLeafyBranches option.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Expressions now support bindings keys that look like zero arg functions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SpanWithinQuery and SpanContainingQuery that return spans inside of / containing another spans.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New Spatial "Geo3d" API with partial Spatial4j integration. It is a set of shapes implemented using 3D planar geometry for calculating spatial relations on the surface of a sphere. Shapes include Point, BBox, Circle, Path (buffered line string), and Polygon.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 5.1.0 release.&lt;/p&gt;

+&lt;h3 id="highlights-of-the-lucene-release-include"&gt;Highlights of the Lucene release include:&lt;/h3&gt;
+&lt;p&gt;Stronger index safety&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;All file access now uses Java’s NIO.2 APIs which give Lucene stronger index safety in terms of better error handling and safer commits.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Every Lucene segment now stores a unique id per-segment and per-commit to aid in accurate replication of index files.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;During merging, IndexWriter now always checks the incoming segments for corruption before merging. This can mean, on upgrading to 5.0.0, that merging may uncover long-standing latent corruption in an older 4.x index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Reduced heap usage&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now supports random-writable and advance-able sparse bitsets (RoaringDocIdSet and SparseFixedBitSet), so the heap required is in proportion to how many bits are set, not how many total documents exist in the index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Heap usage during IndexWriter merging is also much lower with the new Lucene50Codec, since doc values and norms for the segments being merged are no longer fully loaded into heap for all fields; now they are loaded for the one field currently being merged, and then dropped.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default norms format now uses sparse encoding when appropriate, so indices that enable norms for many sparse fields will see a large reduction in required heap at search time.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;5.0 has a new API to print a tree structure showing a recursive breakdown of which parts are using how much heap.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Other features&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;FieldCache is gone (moved to a dedicated UninvertingReader in the misc module). This means when you intend to sort on a field, you should index that field using doc values, which is much faster and less heap consuming than FieldCache.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Tokenizers and Analyzers no longer require Reader on init.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;NormsFormat now gets its own dedicated NormsConsumer/Producer&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SortedSetSortField, used to sort on a multi-valued field, is promoted from sandbox to Lucene's core.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;PostingsFormat now uses a "pull" API when writing postings, just like doc values. This is powerful because you can do things in your postings format that require making more than one pass through the postings such as iterating over all postings for each term to decide which compression format it should use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New DateRangeField type enables Indexing and searching of date ranges, particularly multi-valued ones.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new ExitableDirectoryReader extends FilterDirectoryReader and enables exiting requests that take too long to enumerate over terms.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Suggesters from multi-valued field can now be built as DocumentDictionary now enumerates each value separately in a multi-valued field.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;ConcurrentMergeScheduler detects whether the index is on SSD or not and does a better job defaulting its settings. This only works on Linux for now; other OS's will continue to use the previous defaults (tuned for spinning disks).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Auto-IO-throttling has been added to ConcurrentMergeScheduler, to rate limit IO writes for each merge depending on incoming merge rate.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CustomAnalyzer has been added that allows to configure analyzers like you do in Solr's index schema. This class has a builder API to configure Tokenizers, TokenFilters, and CharFilters based on their SPI names and parameters as documented by the corresponding factories.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Memory index now supports payloads.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a filter cache with a usage tracking policy that caches filters based on frequency of use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default codec has an option to control BEST_SPEED or BEST_COMPRESSION for stored fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Stored fields are merged more efficiently, especially when upgrading from previous versions or using SortingMergePolicy&lt;/p&gt;
+&lt;/li&gt;

+&lt;p&gt;Apache Lucene is a high-performance, full-featured text search engine
+library written entirely in Java. It is a technology suitable for nearly
+any application that requires full-text search, especially cross-platform.&lt;/p&gt;
+&lt;p&gt;This release contains numerous bug fixes, optimizations, and
+improvements, some of which are highlighted below. The release
+is available for immediate download at:
+&lt;a href="https://lucene.apache.org/core/mirrors-core-latest-redir.html"&gt;https://lucene.apache.org/core/mirrors-core-latest-redir.html&lt;/a&gt;&lt;/p&gt;
+&lt;p&gt;Lucene 5.0 Release Highlights:&lt;/p&gt;
+&lt;p&gt;Stronger index safety&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;All file access now uses Java’s NIO.2 APIs which give Lucene stronger index safety in terms of better error handling and safer commits.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Every Lucene segment now stores a unique id per-segment and per-commit to aid in accurate replication of index files.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;During merging, IndexWriter now always checks the incoming segments for corruption before merging. This can mean, on upgrading to 5.0.0, that merging may uncover long-standing latent corruption in an older 4.x index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Reduced heap usage&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now supports random-writable and advance-able sparse bitsets (RoaringDocIdSet and SparseFixedBitSet), so the heap required is in proportion to how many bits are set, not how many total documents exist in the index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Heap usage during IndexWriter merging is also much lower with the new Lucene50Codec, since doc values and norms for the segments being merged are no longer fully loaded into heap for all fields; now they are loaded for the one field currently being merged, and then dropped.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default norms format now uses sparse encoding when appropriate, so indices that enable norms for many sparse fields will see a large reduction in required heap at search time.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;5.0 has a new API to print a tree structure showing a recursive breakdown of which parts are using how much heap.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Other features&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;FieldCache is gone (moved to a dedicated UninvertingReader in the misc module). This means when you intend to sort on a field, you should index that field using doc values, which is much faster and less heap consuming than FieldCache.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Tokenizers and Analyzers no longer require Reader on init.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;NormsFormat now gets its own dedicated NormsConsumer/Producer&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SortedSetSortField, used to sort on a multi-valued field, is promoted from sandbox to Lucene's core.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;PostingsFormat now uses a "pull" API when writing postings, just like doc values. This is powerful because you can do things in your postings format that require making more than one pass through the postings such as iterating over all postings for each term to decide which compression format it should use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New DateRangeField type enables Indexing and searching of date ranges, particularly multi-valued ones.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new ExitableDirectoryReader extends FilterDirectoryReader and enables exiting requests that take too long to enumerate over terms.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Suggesters from multi-valued field can now be built as DocumentDictionary now enumerates each value separately in a multi-valued field.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;ConcurrentMergeScheduler detects whether the index is on SSD or not and does a better job defaulting its settings. This only works on Linux for now; other OS's will continue to use the previous defaults (tuned for spinning disks).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Auto-IO-throttling has been added to ConcurrentMergeScheduler, to rate limit IO writes for each merge depending on incoming merge rate.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CustomAnalyzer has been added that allows to configure analyzers like you do in Solr's index schema. This class has a builder API to configure Tokenizers, TokenFilters, and CharFilters based on their SPI names and parameters as documented by the corresponding factories.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Memory index now supports payloads.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a filter cache with a usage tracking policy that caches filters based on frequency of use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default codec has an option to control BEST_SPEED or BEST_COMPRESSION for stored fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Stored fields are merged more efficiently, especially when upgrading from previous versions or using SortingMergePolicy&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;NOTE: Lucene 5 no longer supports the Lucene 3.x index format. Opening indexes will result in IndexFormatTooOldException. It is recommended to either reindex all your data, or upgrade the old indexes with the IndexUpgrader tool of latest Lucene 4 version (4.10.x). Those indexes can then be read (see next section) with Lucene 5.&lt;/p&gt;

+&lt;p&gt;Both releases now require Java 7 or greater (recommended is
+Oracle Java 7 or OpenJDK 7, minimum update 55; earlier versions
+have known JVM bugs affecting Lucene and Solr). In addition,
+both are fully compatible with Java 8.&lt;/p&gt;
+&lt;p&gt;See the &lt;a href="/core/4_8_0/changes/Changes.html"&gt;Lucene CHANGES.txt&lt;/a&gt; and
+&lt;a href="/solr/4_8_0/changes/Changes.html"&gt;Solr CHANGES.txt&lt;/a&gt; files included
+with the release for a full list of details.&lt;/p&gt;
+&lt;h3 id="highlights-of-the-lucene-release-include"&gt;Highlights of the Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;All index files now store end-to-end checksums, which are
+  now validated during merging and reading. This ensures that
+  corruptions caused by any bit-flipping hardware problems or bugs
+  in the JVM can be detected earlier.  For full detection be sure
+  to enable all checksums during merging (it's disabled by default).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene has a new Rescorer/QueryRescorer API to perform second-pass
+  rescoring or reranking of search results using more expensive scoring
+  functions after first-pass hit collection.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;AnalyzingInfixSuggester now supports near-real-time autosuggest.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Simplified impact-sorted postings (using SortingMergePolicy and
+  EarlyTerminatingCollector) to use Lucene's Sort class
+  to express the sort order.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Bulk scoring and normal iterator-based scoring were separated,
+  so some queries can do bulk scoring more effectively.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Switched to MurmurHash3 to hash terms during indexing.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter now supports updating of binary doc value fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HunspellStemFilter now uses 10 to 100x less RAM. It also loads
+  all known OpenOffice dictionaries without error.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now also fsyncs the directory metadata on commits, if the
+  operating system and file system allow it (Linux, MacOSX are
+  known to work).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now uses Java 7 file system functions under the hood,
+  so index files can be deleted on Windows, even when readers are
+  still open.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A serious bug in NativeFSLockFactory was fixed, which could
+  allow multiple IndexWriters to acquire the same lock.  The
+  lock file is no longer deleted from the index directory
+  even when the lock is not held.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h3 id="highlights-of-the-solr-release-include"&gt;Highlights of the Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;&lt;code class="inline"&gt;&amp;lt;fields&amp;gt;&lt;/code&gt; and &lt;code class="inline"&gt;&amp;lt;types&amp;gt;&lt;/code&gt; tags have been deprecated from schema.xml.
+  There is no longer any reason to keep them in the schema file,
+  they may be safely removed. This allows intermixing of &lt;code class="inline"&gt;&amp;lt;fieldType&amp;gt;&lt;/code&gt;,
+  &lt;code class="inline"&gt;&amp;lt;field&amp;gt;&lt;/code&gt; and &lt;code class="inline"&gt;&amp;lt;copyField&amp;gt;&lt;/code&gt; definitions if desired.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+improvements, some of which are highlighted below. The release
+is available for immediate download at:
+  &lt;a href="https://lucene.apache.org/core/mirrors-core-latest-redir.html"&gt;https://lucene.apache.org/core/mirrors-core-latest-redir.html&lt;/a&gt;&lt;/p&gt;

+&lt;h3 id="lucene-480-release-highlights"&gt;Lucene 4.8.0 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Apache Lucene now requires Java 7 or greater (recommended is
+  Oracle Java 7 or OpenJDK 7, minimum update 55; earlier versions
+  have known JVM bugs affecting Lucene).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Apache Lucene is fully compatible with Java 8.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;All index files now store end-to-end checksums, which are
+  now validated during merging and reading. This ensures that
+  corruptions caused by any bit-flipping hardware problems or bugs
+  in the JVM can be detected earlier.  For full detection be sure
+  to enable all checksums during merging (it's disabled by default).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene has a new Rescorer/QueryRescorer API to perform second-pass
+  rescoring or reranking of search results using more expensive scoring
+  functions after first-pass hit collection.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;AnalyzingInfixSuggester now supports near-real-time autosuggest.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Simplified impact-sorted postings (using SortingMergePolicy and
+  EarlyTerminatingCollector) to use Lucene's Sort class
+  to express the sort order.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Bulk scoring and normal iterator-based scoring were separated,
+  so some queries can do bulk scoring more effectively.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Switched to MurmurHash3 to hash terms during indexing.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter now supports updating of binary doc value fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HunspellStemFilter now uses 10 to 100x less RAM. It also loads
+  all known OpenOffice dictionaries without error.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now also fsyncs the directory metadata on commits, if the
+  operating system and file system allow it (Linux, MacOSX are
+  known to work).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now uses Java 7 file system functions under the hood,
+  so index files can be deleted on Windows, even when readers are
+  still open.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A serious bug in NativeFSLockFactory was fixed, which could
+  allow multiple IndexWriters to acquire the same lock.  The
+  lock file is no longer deleted from the index directory
+  even when the lock is not held.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 4.7.2 release.&lt;/p&gt;

+&lt;p&gt;A new migrate collection API to split all documents with a route key
+  into another collection.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added support for tri-level compositeId routing.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Admin UI - Added a new Files conf directory browser/file viewer.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add a QParserPlugin for Lucene's SimpleQueryParser.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Suggest improvements: a new SuggestComponent that fully utilizes the
+  Lucene suggester module; queries can now use multiple suggesters;
+  Lucene's FreeTextSuggester and BlendedInfixSuggester are now supported.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New cursorMark request param for efficient deep paging of sorted
+  result sets. See &lt;a href="http://s.apache.org/cursorpagination"&gt;http://s.apache.org/cursorpagination&lt;/a&gt;&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add a Solr contrib that allows for building Solr indexes via Hadoop's
+  MapReduce.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Upgrade to Spatial4j 0.4. Various new options are now exposed

+&lt;h3 id="lucene-47-release-highlights"&gt;Lucene 4.7 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;When sorting by String (SortField.STRING), you can now specify whether missing values should be sorted first (the default), or last.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add two memory resident dictionaries (FST terms dictionary and FSTOrd
+  terms dictionary) to improve primary key lookups. The
+  PostingsBaseFormat API is also changed so that term dictionaries get
+  the ability to block encode term metadata, and all dictionary
+  implementations can now plug in any PostingsBaseFormat.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;NRT support for file systems that do not have delete on last close or cannot delete while referenced semantics.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add LongBitSet for managing more than 2.1B bits (otherwise use FixedBitSet).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Speed up Lucene range faceting from O(N) per hit to O(log(N)) per hit using segment trees.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SearcherTaxonomyManager over search and taxonomy index directories
+  (i.e. not only NRT).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Drilling down or sideways on a Lucene facet range (using
+  Range.getFilter()) is now faster for costly filters (uses random
+  access, not iteration); range facet counts now accept a fast-match
+  filter to avoid computing the value for documents that are out of
+  bounds, e.g. using a bounding box filter with distance range faceting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add Analyzer for Kurdish.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add Payload support to FileDictionary (Suggest) and make it more configurable.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add a new BlendedInfixSuggester, which is like AnalyzingInfixSuggester but boosts suggestions that matched tokens with lower positions.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SimpleQueryParser: parser for human-entered queries.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add multitermquery (wildcards,prefix,etc) to PostingsHighlighter.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Upgrade to Spatial4j 0.4.1: Parses WKT (including ENVELOPE) with extension BUFFER; buffering a point results in a Circle. JTS isn't
+  needed for WKT any more but remains required for Polygons. New Shapes: ShapeCollection and BufferedLineString.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add spatial SerializedDVStrategy that serializes a binary
+  representation of a shape into BinaryDocValues. It supports exact
+  geometry relationship calculations.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 4.6.1 release.&lt;/p&gt;

+&lt;h3 id="highlights-of-the-lucene-release-include"&gt;Highlights of the Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Added support for missing values to DocValues fields through
+  AtomicReader.getDocsWithField.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene 4.5 has a new Lucene45Codec with Lucene45DocValues, supporting missing
+  values and with most datastructures residing off-heap.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New in-memory DocIdSet implementations which are especially better than
+  FixedBitSet on small sets: WAH8DocIdSet, PFORDeltaDocIdSet and EliasFanoDocIdSet.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CachingWrapperFilter now caches filters with WAH8DocIdSet by default, which
+  has the same memory usage as FixedBitSet in the worst case but is smaller and faster on small sets.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;TokenStreams now set the position increment in end(), so we can handle trailing holes.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter no longer clones the given IndexWriterConfig.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Lucene 4.5 also includes numerous optimizations and bugfixes.&lt;/p&gt;
+&lt;h3 id="highlights-of-the-solr-release-include"&gt;Highlights of the Solr release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Custom sharding support, including the ability to shard by field.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;DocValue improvements: single valued fields no longer require a default
+  value, allowiing dynamicFields to contain doc values, as well as
+  sortMissingFirst and sortMissingLast on docValue fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Ability to store solr.xml in ZooKeeper.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Multithreaded faceting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CloudSolrServer can now route updates directly to the appropriate shard
+  leader.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Solr 4.5 also includes numerous optimizations and bugfixes.&lt;/p&gt;</content><category term="news"></category></entry><entry><title>PyLucene 4.4.0-1 available</title><link href="/" rel="alternate"></link><published>2013-08-23T00:00:00+00:00</published><updated>2013-08-23T00:00:00+00:00</updated><author><name>Lucene and Solr Developers</name></author><id>tag:None,2013-08-23:/</id><content type="html">&lt;p&gt;This release tracks Lucene Core's recent 4.4.0 &lt;a href="https://lu [...]

+&lt;h3 id="lucene-840-release-highlights"&gt;Lucene 8.4.0 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;LatLonShape now supports the "CONTAINS" relation, which enables to find all indexed shapes that contain the query shape.&lt;/li&gt;
+&lt;li&gt;Concurrent search is getting more efficient by allowing collectors to share information across threads in order to more efficiently skip non-competitive hits.&lt;/li&gt;
+&lt;li&gt;Faster FST lookups on dense nodes.&lt;/li&gt;
+&lt;li&gt;Postings are now decoded using SIMD instructions.&lt;/li&gt;
+&lt;li&gt;LRUQueryCache includes new heuristics that prevent caching from hurting latency too much.&lt;/li&gt;
+&lt;li&gt;LatLonShape builds a more efficient tree that is expected to translate into search speed improvements.&lt;/li&gt;
+&lt;li&gt;BaseDirectoryReader no longer sums up document counts across leaves eagerly, allowing for more efficient reader views that hide a subset of documents.&lt;/li&gt;
+&lt;li&gt;The index on top of BKD trees is now stored off-heap with MMapDirectory.&lt;/li&gt;
+&lt;li&gt;Simple Intervals queries support highlighting.&lt;/li&gt;
+&lt;li&gt;Reading DocValues can be interrupted when timeout is exceeded.&lt;/li&gt;

+&lt;ul&gt;
+&lt;li&gt;New SpanishMinimalStemFilter&lt;/li&gt;
+&lt;li&gt;New "export all terms and doc freqs" feature to Luke with delimiters&lt;/li&gt;
+&lt;li&gt;Composite Matches from multiple subqueries now allow access to their submatches, and a new NamedMatches API allows marking of subqueries and a simple way to find which subqueries have matched on a given&lt;/li&gt;
+&lt;li&gt;Range Query For Multiple Connected Ranges&lt;/li&gt;
+&lt;li&gt;LatLonDocValuesPointInPolygonQuery for LatLonDocValuesField&lt;/li&gt;
+&lt;li&gt;New UniformSplitPostingsFormat (name "UniformSplit") primarily benefiting in simplicity and extensibility&lt;/li&gt;
+&lt;li&gt;New STUniformSplitPostingsFormat (name "SharedTermsUniformSplit") that shares a single internal term dictionary across fields&lt;/li&gt;
+&lt;li&gt;DisjunctionMaxQuery more efficiently leverages impacts to skip non-competitive hits&lt;/li&gt;
+&lt;li&gt;BooleanQuery with no scoring clause can now early terminate the query when the total hits is not requested&lt;/li&gt;
+&lt;li&gt;Matches on wildcard queries will defer building their full disjunction until a MatchesIterator is pulled&lt;/li&gt;
+&lt;li&gt;spatial-extras quad and packed quad prefix trees now index points faster&lt;/li&gt;
+&lt;li&gt;Add additional leaf node level optimizations in LatLonShapeBoundingBoxQuery&lt;/li&gt;
+&lt;li&gt;Improve performance of WITHIN and DISJOINT queries for Shape queries by doing just one pass whenever possible&lt;/li&gt;
+&lt;li&gt;Introduce shared count based early termination across multiple slices&lt;/li&gt;
+&lt;li&gt;Blocktree's seekExact now short-circuits false if the term isn't in the min-max range of the segment. Large perf gain for ID/time like data when populated sequentially&lt;/li&gt;
+&lt;li&gt;Show SPI names instead of class names in Luke Analysis tab&lt;/li&gt;
+&lt;li&gt;GraphTokenStreamFiniteStrings preserves all Token attributes through its finite strings TokenStreams&lt;/li&gt;
+&lt;li&gt;Introduced SpanPositionRange into XML Query Parser&lt;/li&gt;
+&lt;li&gt;Use a sort key instead of true distance in NearestNeighbor&lt;/li&gt;
+&lt;li&gt;Tessellator labels the edges of the generated triangles whether they belong to the original polygon&lt;/li&gt;
+&lt;li&gt;Use exact distance between point and bounding rectangle in FloatPointNearestNeighbor&lt;/li&gt;
+&lt;li&gt;The Korean analyzer now splits tokens on boundaries between digits and alphabetic characters&lt;/li&gt;

+&lt;h3 id="lucene-800-release-highlights"&gt;Lucene 8.0.0 Release Highlights:&lt;/h3&gt;
+&lt;h4 id="query-execution"&gt;Query execution&lt;/h4&gt;
+&lt;p&gt;Term queries, phrase queries and boolean queries introduced new optimization that enables efficient skipping over non-competitive documents when the total hit count is not needed. Depending on the exact query and data distribution, queries might run between a few percents slower and many times faster, especially term queries and pure disjunctions.&lt;/p&gt;
+&lt;p&gt;In order to support this enhancement, some API changes have been made:
+ * TopDocs.totalHits is no longer a long but an object that gives a lower bound of the actual hit count.
+ * IndexSearcher's search and searchAfter methods now only compute total hit counts accurately up to 1,000 in order to enable this optimization by default.
+ * Queries are now required to produce non-negative scores.&lt;/p&gt;
+&lt;h4 id="codecs"&gt;Codecs&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Postings now index score impacts alongside skip data. This is how term queries optimize collection of top hits when hit counts are not needed.&lt;/li&gt;
+&lt;li&gt;Doc values introduced jump tables, so that advancing runs in constant time. This is especially helpful on sparse fields.&lt;/li&gt;
+&lt;li&gt;The terms index FST is now loaded off-heap for non-primary-key fields using MMapDirectory, reducing heap usage for such fields.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="custom-scoring"&gt;Custom scoring&lt;/h4&gt;
+&lt;p&gt;The new FeatureField allows efficient integration of static features such as a pagerank into the score. Furthermore, the new LongPoint#newDistanceFeatureQuery and LatLonPoint#newDistanceFeatureQuery methods allow boosting by recency and geo-distance respectively. These new helpers are optimized for the case when total hit counts are not needed. For instance if the pagerank has a significant weight in your scores, then Lucene might be able to skip over documents that have a low p [...]

+&lt;h3 id="lucene-770-release-highlights"&gt;Lucene 7.7.0 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;Fix LatLonShape WITHIN queries that fail with Multiple search Polygons that share the dateline.&lt;/li&gt;
+&lt;li&gt;LatLonShape's within and disjoint queries can return false positives with indexed multi-shapes.&lt;/li&gt;
+&lt;li&gt;ExitableDirectoryReader may now time out queries that run on points such as range queries or geo queries.&lt;/li&gt;
+&lt;li&gt;StandardTokenizer and UAX29URLEmailTokenizer now support Unicode 9.0, and provide Unicode UTS#51 v11.0 Emoji tokenization with the "&lt;EMOJI&gt;" token type.&lt;/li&gt;
+&lt;li&gt;TopFieldCollector can now early-terminates queries when sorting by SortField.DOC.&lt;/li&gt;
+&lt;li&gt;Speed up merging segments of points with data dimensions by only sorting on the indexed dimensions.&lt;/li&gt;
+&lt;li&gt;The KoreanTokenizer no longer splits unknown words on combining diacritics and detects script boundaries more accurately with Character#UnicodeScript#of.&lt;/li&gt;
+&lt;li&gt;Change LatLonShape encoding to use 4 bytes Per Dimension.&lt;/li&gt;
+&lt;li&gt;BufferedUpdates now uses an optimized storage for buffering docvalues updates that can save up to 80% of the heap used compared to the previous implementation and uses non-object based datastructures.&lt;/li&gt;
+&lt;li&gt;Moved to the default accepted overhead ratio for packet ints in DocValuesFieldUpdates yields an up-to 4x performance improvement when applying doc values updates.&lt;/li&gt;
+&lt;li&gt;Doc-value updates get applied faster by sorting with quicksort, rather than an in-place mergesort, which needs to perform fewer swaps.&lt;/li&gt;
+&lt;li&gt;Decrease I/O pressure when merging high dimensional points.&lt;/li&gt;

+&lt;li&gt;New LatLonShapeLineQuery queries indexed shapes with arbitrary lines.&lt;/li&gt;
+&lt;li&gt;analyzeGraphPhrase query builder creates one phrase query per finite strings in the graph based on slop parameter.&lt;/li&gt;

+&lt;h3 id="lucene-700-release-highlights"&gt;Lucene 7.0.0 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Doc values switched from random access to iterators.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The 7.0 codec now sparsely encodes sparse doc values and length normalization factors ("norms"), which also translates to optimization in both indexing, and search on sparse values. With these changes, you finally only pay for what you actually use with doc values, in index size, indexing performance, etc.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index time boost for documents is now removed.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Substantial performance gains for delete and update heavy Lucene usage; see http://blog.mikemccandless.com/2017/07/lucene-gets-concurrent-deletes-and.html for details&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Query scoring is now simpler with removal of coord factor, and query normalization.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Classic query parser no longer splits on whitespaces.  This enables better multi-word synonym support.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The version of Lucene that created the index segment would be recorded, along with the version that last modified the index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter, used to add, update and delete documents in your index, will no longer accept broken token offsets sometimes produced by mis-behaving token filters.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexReader exposes methods that are typically used to manage resources whose lifetime needs to mimic the lifetime of segments/indexes, typically caches. They have been made much less trappy.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The dimensional points API now takes a field name up front to offer per-field points access, matching how the doc values APIs work.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The PostingsHighlighter was removed.  Migrating to the UnifiedHighlighter should be straight-forward.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Apache Lucene was tested to be fully compatible with the release of Java 9 and its module system Jigsaw, coming out tomorrow on September 21st!&lt;/p&gt;</content><category term="core/news"></category></entry><entry><title>Apache Lucene™ 6.6.1 available</title><link href="/" rel="alternate"></link><published>2017-09-07T00:00:00+00:00</published><updated>2017-09-07T00:00:00+00:00</updated><author><name>Lucene and Solr Developers</name></author><id>tag:None,2017-09-07:/</id><summa [...]

+&lt;p&gt;A new PatternTokenizer that uses Lucene's RegExp implementation&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;RangeFieldQuery now supports CROSSES relation&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new IndexOrDocValuesQuery that uses either an index (points or terms) or doc values in order to run a (range, geo box and distance) query, depending which one is more efficient&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;index-time boosts are deprecated&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Term filters are no longer cached&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Compound filters are cached earlier than regular queries&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;BKDReader now calls grow on larger increments&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;LatLonPointInPolygonQuery are faster&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;LatLonPointDistanceQuery now skips distance computations more often&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;To-parent block joins now implements two-phase iteration&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Point ranges that match most documents are faster&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;PointValues#estimatePointCount is faster with Relation.CELL_INSIDE_QUERY&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Segments are now also sorted during flush, and merging on a sorted index is substantially faster by using some of the same bulk merge optimizations that non-sorted merging uses&lt;/p&gt;
+&lt;/li&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene's best efforts to un-map memory mapped files with "MMapDirectory" now work with the latest Java9 early access builds&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new similarity "BooleanSimilarity" that gives terms a score that is equal to their query boost&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The axiomatic family of similarities (6 in total) based on https://www.eecis.udel.edu/~hfang/pubs/sigir05-axiom.pdf&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new token filter "SynonymGraphFilter" that outputs a correct graph structure for multi-token synonyms at query time&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Graph token streams, such as those produced by the "SynonymGraphFilter", are now handled accurately by query parsers&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new collector "DocValuesStatsCollector" gives the ability to compute statistics on DocValues field&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;It is now possible to filter "SortedDocValues" and "SortedSetDocValues" terms enum with a compiled automaton&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The "UnifiedHighlighter" can now highlight fields with queries that don't necessarily refer to that field&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;DrillSideways can now run queries concurrently&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index sorting now supports sorting on multi-valued fields using MIN, MAX, etc. selectors&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Points do not store the implicit split dimension in the 1-dimension case. This saves between 6% memory for the largest types such an InetAddressPoint to 33% for the smaller types such as HalfFloatPoint.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The BKD in-memory index for dimensional points now uses a compressed format, using substantially less RAM in some cases&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The BKD writing now buffers each leaf block in heap before writing to disk, giving a small speedup in points-heavy use cases&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;"TermAutomatonQuery" now rewrites to more efficient queries when possible&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Please note, this release cannot be built from source with Java 8 update 121,
+use an earlier version instead! This is caused by a bug introduced into the
+Javadocs tool shipped with that update. The workaround was too late for this
+Lucene release. Of course, you can use the binary artifacts.&lt;/p&gt;</content><category term="core/news"></category></entry><entry><title>Apache Lucene™ 6.3.0 available</title><link href="/" rel="alternate"></link><published>2016-11-08T00:00:00+00:00</published><updated>2016-11-08T00:00:00+00:00</updated><author><name>Lucene and Solr Developers</name></author><id>tag:None,2016-11-08:/</id><summary type="html">&lt;p&gt;The Lucene PMC is pleased to announce the release of Apache Lucene 6 [...]

+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;A brand new "UnifiedHighlighter" derivative of the PostingsHighlighter that can consume offsets from postings, term vectors, or analysis. It can highlight phrases as accurately as the standard Highlighter. Light term vectors can be used with offsets in postings for fast wildcard (MultiTermQuery) highlighting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SimpleQueryParser now parses '*' to MatchAllDocsQuery&lt;/p&gt;

+&lt;li&gt;
+&lt;p&gt;FuzzyQuery now matches all terms within the specified edit distance, even if they are short terms&lt;/p&gt;

+&lt;h3 id="highlights-of-this-lucene-release-include"&gt;Highlights of this Lucene release include:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;The CREATE_NEW flag is passed when creating a file to ensure Lucene is really write-once&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index numeric ranges (min and max value in a single field) and search by overlapping range&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter methods return a sequence number indicating effective order of operations across threads&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;UkrainianMorfologikAnalyzer is a new dictionary based analyzer for the Ukrainian language&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The Polygon class can now be created from a GeoJSON string&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Compound file creation now verifies checksum of its component files&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Index time sorting is now a core feature, and supports dimensional points&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;StandardAnalyzer is moved to core and is the default analyzer&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MatchNoDocsQuery now includes the reason it was created&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;QueryParser can now be told to not pre-split on whitespace&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MMapDirectory tries harder to prevent SIGSEGV if buggy code tries to execute
+    searches after the index was closed, but it's still best effort&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;MMapDirectory no longer allocates weak references to ease garbage collection&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Conjunction (MUST, FILTER) queries are faster&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+&lt;p&gt;Lucene 6.1.0 Release Highlights:&lt;/p&gt;
+&lt;p&gt;New features&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Numerous improvements to LatLonPoint, for indexing a latitude/longitude point and searching by polygon, distance or box, or finding nearest neighbors&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Geo3D now has simple APIs for creating common shape queries, matching LatLonPoint&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Optimizations&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Faster indexing and searching of points.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Faster geo-spatial indexing and searching for LatLonPoint, Geo3D and GeoPoint (see http://home.apache.org/~mikemccand/geobench.html )&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HardlinkCopyDirectoryWrapper optimizes file copies using hard links&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;In case of contention, the query cache now prefers returning an uncached Scorer rather than waiting on a lock.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Bug fixes&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;BooleanQuery could sometimes assign too low scores to ranges of documents that matched a single clause.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Doc values updates could sometimes be applied in the wrong order.&lt;/p&gt;

+&lt;h4 id="api-changes"&gt;API Changes&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;PhraseQuery and BooleanQuery are now immutable&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="new-features"&gt;New features&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Added a new org.apache.lucene.search.join.CheckJoinIndex class that can be used to validate that an index has an appropriate structure to run join queries&lt;/li&gt;
+&lt;li&gt;Added a new BlendedTermQuery to blend statistics across several terms&lt;/li&gt;
+&lt;li&gt;New common suggest API that mirrors Lucene's Query/IndexSearcher APIs for Document based suggester.&lt;/li&gt;
+&lt;li&gt;IndexWriter can now be initialized from an already open near-real-time or non-NRT reader&lt;/li&gt;
+&lt;li&gt;Add experimental range tree doc values format and queries, based on a 1D version of the spatial BKD tree, for a faster and smaller alternative to postings-based numeric and binary term filtering.  Range trees can also handle values larger than 64 bits.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="geo-related-features-and-improvements"&gt;Geo-related features and improvements&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Added GeoPointField, GeoPointInBBoxQuery, GeoPointInPolygonQuery for simple "indexed lat/lon point in bbox/shape" searching&lt;/li&gt;
+&lt;li&gt;Added experimental BKD geospatial tree doc values format and queries, for fast "bbox/polygon contains lat/lon points"&lt;/li&gt;
+&lt;li&gt;Use doc values to post-filter GeoPointField hits that fall in boundary cells, resulting in smaller index, faster searches and less heap used for each query&lt;/li&gt;
+&lt;/ul&gt;
+&lt;h4 id="optimizations"&gt;Optimizations&lt;/h4&gt;
+&lt;ul&gt;
+&lt;li&gt;Reduce RAM usage of FieldInfos, and speed up lookup by number, by using an array instead of TreeMap except in very sparse cases&lt;/li&gt;
+&lt;li&gt;Faster intersection of the terms dictionary with very finite automata, which can be generated eg. by simple regexp queries&lt;/li&gt;
+&lt;li&gt;Various bugfixes and optimizations since the 5.2.0 release.&lt;/li&gt;

+&lt;p&gt;Lucene 5.2.0 release highlights:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Span queries now share document conjunction/intersection code with boolean queries, and use two-phased iterators for faster intersection by avoiding loading positions in certain cases.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added two-phase support to SpanNotQuery, and SpanPositionCheckQuery and its subclasses: SpanPositionRangeQuery, SpanPayloadCheckQuery, SpanNearPayloadCheckQuery, SpanFirstQuery.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a new query time join to the join module that uses global ordinals, which is faster for subsequent joins between reopens.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New CompositeSpatialStrategy combines speed of RPT with accuracy of SDV. Includes optimized Intersect predicate to avoid many geometry checks. Uses TwoPhaseIterator.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New LimitTokenOffsetFilter that limits tokens to those before a configured maximum start offset.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New spatial PackedQuadPrefixTree, a generally more efficient choice than QuadPrefixTree, especially for high precision shapes. When used, you should typically disable RPT's pruneLeafyBranches option.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Expressions now support bindings keys that look like zero arg functions&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SpanWithinQuery and SpanContainingQuery that return spans inside of / containing another spans.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New Spatial "Geo3d" API with partial Spatial4j integration. It is a set of shapes implemented using 3D planar geometry for calculating spatial relations on the surface of a sphere. Shapes include Point, BBox, Circle, Path (buffered line string), and Polygon.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;

+&lt;p&gt;Lucene 5.0 Release Highlights:&lt;/p&gt;
+&lt;p&gt;Stronger index safety&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;All file access now uses Java’s NIO.2 APIs which give Lucene stronger index safety in terms of better error handling and safer commits.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Every Lucene segment now stores a unique id per-segment and per-commit to aid in accurate replication of index files.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;During merging, IndexWriter now always checks the incoming segments for corruption before merging. This can mean, on upgrading to 5.0.0, that merging may uncover long-standing latent corruption in an older 4.x index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Reduced heap usage&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now supports random-writable and advance-able sparse bitsets (RoaringDocIdSet and SparseFixedBitSet), so the heap required is in proportion to how many bits are set, not how many total documents exist in the index.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Heap usage during IndexWriter merging is also much lower with the new Lucene50Codec, since doc values and norms for the segments being merged are no longer fully loaded into heap for all fields; now they are loaded for the one field currently being merged, and then dropped.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default norms format now uses sparse encoding when appropriate, so indices that enable norms for many sparse fields will see a large reduction in required heap at search time.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;5.0 has a new API to print a tree structure showing a recursive breakdown of which parts are using how much heap.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;Other features&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;FieldCache is gone (moved to a dedicated UninvertingReader in the misc module). This means when you intend to sort on a field, you should index that field using doc values, which is much faster and less heap consuming than FieldCache.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Tokenizers and Analyzers no longer require Reader on init.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;NormsFormat now gets its own dedicated NormsConsumer/Producer&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;SortedSetSortField, used to sort on a multi-valued field, is promoted from sandbox to Lucene's core.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;PostingsFormat now uses a "pull" API when writing postings, just like doc values. This is powerful because you can do things in your postings format that require making more than one pass through the postings such as iterating over all postings for each term to decide which compression format it should use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;New DateRangeField type enables Indexing and searching of date ranges, particularly multi-valued ones.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A new ExitableDirectoryReader extends FilterDirectoryReader and enables exiting requests that take too long to enumerate over terms.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Suggesters from multi-valued field can now be built as DocumentDictionary now enumerates each value separately in a multi-valued field.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;ConcurrentMergeScheduler detects whether the index is on SSD or not and does a better job defaulting its settings. This only works on Linux for now; other OS's will continue to use the previous defaults (tuned for spinning disks).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Auto-IO-throttling has been added to ConcurrentMergeScheduler, to rate limit IO writes for each merge depending on incoming merge rate.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;CustomAnalyzer has been added that allows to configure analyzers like you do in Solr's index schema. This class has a builder API to configure Tokenizers, TokenFilters, and CharFilters based on their SPI names and parameters as documented by the corresponding factories.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Memory index now supports payloads.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Added a filter cache with a usage tracking policy that caches filters based on frequency of use.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;The default codec has an option to control BEST_SPEED or BEST_COMPRESSION for stored fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Stored fields are merged more efficiently, especially when upgrading from previous versions or using SortingMergePolicy&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;NOTE: Lucene 5 no longer supports the Lucene 3.x index format. Opening indexes will result in IndexFormatTooOldException. It is recommended to either reindex all your data, or upgrade the old indexes with the IndexUpgrader tool of latest Lucene 4 version (4.10.x). Those indexes can then be read (see next section) with Lucene 5.&lt;/p&gt;

+&lt;h3 id="lucene-480-release-highlights"&gt;Lucene 4.8.0 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Apache Lucene now requires Java 7 or greater (recommended is
+  Oracle Java 7 or OpenJDK 7, minimum update 55; earlier versions
+  have known JVM bugs affecting Lucene).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Apache Lucene is fully compatible with Java 8.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;All index files now store end-to-end checksums, which are
+  now validated during merging and reading. This ensures that
+  corruptions caused by any bit-flipping hardware problems or bugs
+  in the JVM can be detected earlier.  For full detection be sure
+  to enable all checksums during merging (it's disabled by default).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene has a new Rescorer/QueryRescorer API to perform second-pass
+  rescoring or reranking of search results using more expensive scoring
+  functions after first-pass hit collection.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;AnalyzingInfixSuggester now supports near-real-time autosuggest.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Simplified impact-sorted postings (using SortingMergePolicy and
+  EarlyTerminatingCollector) to use Lucene's Sort class
+  to express the sort order.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Bulk scoring and normal iterator-based scoring were separated,
+  so some queries can do bulk scoring more effectively.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Switched to MurmurHash3 to hash terms during indexing.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;IndexWriter now supports updating of binary doc value fields.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;HunspellStemFilter now uses 10 to 100x less RAM. It also loads
+  all known OpenOffice dictionaries without error.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now also fsyncs the directory metadata on commits, if the
+  operating system and file system allow it (Linux, MacOSX are
+  known to work).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Lucene now uses Java 7 file system functions under the hood,
+  so index files can be deleted on Windows, even when readers are
+  still open.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;A serious bug in NativeFSLockFactory was fixed, which could
+  allow multiple IndexWriters to acquire the same lock.  The
+  lock file is no longer deleted from the index directory
+  even when the lock is not held.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 4.7.2 release.&lt;/p&gt;

+&lt;p&gt;The next release will also contain some improvements for Java 7:&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;Better file handling (especially on Windows) in the directory implementations. Files can now be deleted on windows, although the index is still open - like it was always possible on Unix environments (delete on last close semantics).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Speed improvements in sorting comparators: Sorting now uses Java 7's own comparators for integer and long sorts, which are highly optimized by the Hotspot VM.&lt;/p&gt;
+&lt;/li&gt;
+&lt;/ul&gt;
+&lt;p&gt;If you want to stay up-to-date with Lucene and Solr, you should upgrade your infrastructure to Java 7.
+Please be aware that you must use at least use Java 7u1.
+The recommended version at the moment is Java 7u25. Later versions like 7u40, 7u45,... have a bug causing index corrumption.
+Ideally use the Java 7u60 prerelease, which has fixed this bug. Once 7u60 is out, this will be the recommended version.
+In addition, there is no more Oracle/BEA JRockit available for Java 7, use the official Oracle Java 7.
+JRockit was never working correctly with Lucene/Solr (causing index corrumption), so this should not be an issue.
+Please also review our list of JVM bugs: &lt;a href="http://wiki.apache.org/lucene-java/JavaBugs"&gt;http://wiki.apache.org/lucene-java/JavaBugs&lt;/a&gt;&lt;/p&gt;
+&lt;p&gt;&lt;em&gt;EDIT (as of 15 April 2014):&lt;/em&gt; The recently released Java 7u55 fixes the above bug causing index corrumption.

+&lt;h3 id="lucene-47-release-highlights"&gt;Lucene 4.7 Release Highlights:&lt;/h3&gt;
+&lt;ul&gt;
+&lt;li&gt;
+&lt;p&gt;When sorting by String (SortField.STRING), you can now specify whether missing values should be sorted first (the default), or last.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add two memory resident dictionaries (FST terms dictionary and FSTOrd
+  terms dictionary) to improve primary key lookups. The
+  PostingsBaseFormat API is also changed so that term dictionaries get
+  the ability to block encode term metadata, and all dictionary
+  implementations can now plug in any PostingsBaseFormat.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;NRT support for file systems that do not have delete on last close or cannot delete while referenced semantics.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add LongBitSet for managing more than 2.1B bits (otherwise use FixedBitSet).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Speed up Lucene range faceting from O(N) per hit to O(log(N)) per hit using segment trees.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SearcherTaxonomyManager over search and taxonomy index directories
+  (i.e. not only NRT).&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Drilling down or sideways on a Lucene facet range (using
+  Range.getFilter()) is now faster for costly filters (uses random
+  access, not iteration); range facet counts now accept a fast-match
+  filter to avoid computing the value for documents that are out of
+  bounds, e.g. using a bounding box filter with distance range faceting.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add Analyzer for Kurdish.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add Payload support to FileDictionary (Suggest) and make it more configurable.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add a new BlendedInfixSuggester, which is like AnalyzingInfixSuggester but boosts suggestions that matched tokens with lower positions.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add SimpleQueryParser: parser for human-entered queries.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add multitermquery (wildcards,prefix,etc) to PostingsHighlighter.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Upgrade to Spatial4j 0.4.1: Parses WKT (including ENVELOPE) with extension BUFFER; buffering a point results in a Circle. JTS isn't
+  needed for WKT any more but remains required for Polygons. New Shapes: ShapeCollection and BufferedLineString.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Add spatial SerializedDVStrategy that serializes a binary
+  representation of a shape into BinaryDocValues. It supports exact
+  geometry relationship calculations.&lt;/p&gt;
+&lt;/li&gt;
+&lt;li&gt;
+&lt;p&gt;Various bugfixes and optimizations since the 4.6.1 release.&lt;/p&gt;
+&lt;/li&gt;
