fyi, we might want to upgrade for 3.4 for example. -Vincent

It is a technology suitable for nearly > any application that requires full-text search, especially cross-platform. > > This release contains numerous bug fixes, optimizations, and > improvements, some of which are highlighted below. The release > is available for immediate download at: > > http://www.apache.org/dyn/closer.cgi/lucene/java (see note below). > > See the CHANGES.txt file included with the release for a full list of > details. > > Lucene 3.5.0 Release Highlights: > > * Added a very substantial (3-5X) RAM reduction required to hold the > terms index on opening an IndexReader. (LUCENE-2205) > > * Added IndexSearcher.searchAfter which returns results after a > specified ScoreDoc (e.g. last document on the previous page) to > support deep paging use cases. (LUCENE-2215) > > * Added SearcherManager to manage sharing and reopening IndexSearchers > across multiple search threads. Underlying IndexReader instances are > safely closed if not referenced anymore. (LUCENE-3445, LUCENE-3558) > > * Added SearcherLifetimeManager which safely provides a consistent > view of the index across multiple requests (e.g. paging/drilldown). > (LUCENE-3558, LUCENE-3486) > > * Renamed IndexWriter.optimize to forceMerge to discourage use of > this method since it is horribly costly and rarely justified > anymore. (LUCENE-3439) > > * Added NGramPhraseQuery that speeds up phrase queries 30-50% > when n-gram analysis is used. (LUCENE-3426) > > * Added a new reopen API (IndexReader.openIfChanged) that > returns null instead of the old reader if there are no changes > in the index. (LUCENE-3464) > > * Improvements to vector highlighting: support for more queries > such as wildcards and boundary analysis for generated snippets > (LUCENE-1824, LUCENE-1889) > > * IndexSearcher and IndexReader now perform additional checks to > throw AlreadyClosedExceptions if searches are performed on a > closed IndexReader. Performing searches on already closed reader > can cause JVM crashes when invalid memory mapped files are > referenced. > > * Several bugfixes, including a bug where closing an NRT reader > after the writer was closed was incorrectly invoking the > DeletionPolicy. See CHANGES.txt entries for full details. > > Note: The Apache Software Foundation uses an extensive mirroring network for > distributing releases. It is possible that the mirror you are using may not > have replicated the release yet. If that is the case, please try another > mirror.
