Apache Solr Release Notes

+ +
+ +

Introduction

+

Apache Solr is an open source enterprise search server based on the Apache Lucene Java +search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search, +caching, replication, and a web administration interface. It runs in a Java +servlet container such as Jetty. +

+

See http://lucene.apache.org/solr for more information. +

+

Getting Started

+

You need a Java 1.7 VM or later installed. +In this release, there is an example Solr server including a bundled +servlet container in the directory named "example". +See the tutorial at http://lucene.apache.org/solr/tutorial.html +

+

Release 4.8.0

+
    +
  • Versions of Major Components   (5) +
      +
    1. Apache Tika 1.5 +
      2. +
    2. Carrot2 3.9.0 +
      3. +
    3. Velocity 1.7 and Velocity Tools 2.0 +
      4. +
    4. Apache UIMA 2.3.1 +
      5. +
    5. Apache ZooKeeper 3.4.6 +
      6. +
    +
    • +
  • Upgrading from Solr 4.7   (4) +
      +
    1. In previous versions of Solr, Terms that exceeded Lucene's MAX_TERM_LENGTH were +silently ignored when indexing documents. Begining with Solr 4.8, a document +an error will be generated when attempting to index a document with a term +that is too large. If you wish to continue to have large terms ignored, +use "solr.LengthFilterFactory" in all of your Analyzers. See LUCENE-5472 for +more details. +

      +

      2. +
    2. Solr 4.8 requires Java 7 or greater, Java 8 is verified to be +compatible and may bring some performance improvements. When using +Oracle Java 7 or OpenJDK 7, be sure to not use the GA build 147 or +update versions u40, u45 and u51! We recommend using u55 or later. +An overview of known JVM bugs can be found on +http://wiki.apache.org/lucene-java/JavaBugs +

      +

      3. +
    3. ZooKeeper is upgraded from 3.4.5 to 3.4.6. +

      +

      4. +
    4. <fields> and <types> tags have been deprecated. There is no longer any reason to +keep them in the schema file, they may be safely removed. This allows intermixing of +<fieldType>, <field> and <copyField> definitions if desired. Currently, these tags +are supported so either style may be implemented. TBD is whether they'll be +deprecated formally for 5.0 +

      +

    • Upgrading from Solr 4.6.0   (2) +
        +
      1. CloudSolrServer and LBHttpSolrServer no longer declare MalformedURLException +as thrown from their constructors. +

        +

        2. +
      2. Due to a bug in previous versions the default value of the 'discountOverlap' property +of DefaultSimilarity was not being set appropriately if you were using the implicit +DefaultSimilarityFactory instead of explicitly configuring it. To preserve +consistent behavior for people who upgrade, the implicit behavior is now contingent +on the <luceneMatchVersion/> -- discountOverlap=false for 4.6 and below, +discountOverlap=true for 4.7 and above. See SOLR-5561 for more information. +
