14 September 2011 - Lucene Core 3.4.0 and Solr 3.4.0 Available

The Lucene PMC is pleased to announce the availability of Apache Lucene 3.4.0 and Apache Solr 3.4.0. +

Lucene can be downloaded from http://www.apache.org/dyn/closer.cgi/lucene/java/ and Solr can be downloaded from http://www.apache.org/dyn/closer.cgi/lucene/solr/ +

If you are already using Apache Lucene 3.1, 3.2 or 3.3, we strongly recommend you upgrade to 3.4.0 because of the index corruption bug on OS or computer crash or power loss (LUCENE-3418), now fixed in 3.4.0.

Highlights of the Lucene release include:

Fixed a major bug (LUCENE-3418) whereby a Lucene index could + easily become corrupted if the OS or computer crashed or lost + power.
Added a new faceting module (contrib/facet) for computing facet + counts (both hierarchical and non-hierarchical) at search + time (LUCENE-3079).
Added a new join module (contrib/join), enabling indexing and + searching of nested (parent/child) documents using + BlockJoinQuery/Collector (LUCENE-3171).
It is now possible to index documents with term frequencies + included but without positions (LUCENE-2048); previously + omitTermFreqAndPositions always omitted both.
The modular QueryParser (contrib/queryparser) can now create + NumericRangeQuery.
Added SynonymFilter, in contrib/analyzers, to apply multi-word + synonyms during indexing or querying, including parsers to read + the wordnet and solr synonym formats (LUCENE-3233).
You can now control how documents that don't have a value on the + sort field should sort (LUCENE-3390), using SortField.setMissingValue.
Fixed a case where term vectors could be silently deleted from the + index after addIndexes (LUCENE-3402).

Highlights of the Solr release include:

SolrJ client can now parse grouped and range facets results + (SOLR-2523).
A new XsltUpdateRequestHandler allows posting XML that's + transformed by a provided XSLT into a valid Solr document + (SOLR-2630).
Post-group faceting option (group.truncate) can now compute + facet counts for only the highest ranking documents per-group. + (SOLR-2665).
Add commitWithin update request parameter to all update handlers + that were previously missing it. This tells Solr to commit the + change within the specified amount of time (SOLR-2540).
You can now specify NIOFSDirectory (SOLR-2670).
New parameter hl.phraseLimit speeds up FastVectorHighlighter + (LUCENE-3234).
The query cache and filter cache can now be disabled per request. + See this wiki page + (SOLR-2429).
Improved memory usage, build time, and performance of + SynonymFilterFactory (LUCENE-3233).
Added omitPositions to the schema, so you can omit position + information while still indexing term frequencies (LUCENE-2048).
Various fixes for multi-threaded DataImportHandler.
