Download Apache Lucene Java 2.9.1

The Apache Software Foundation has released a new version of Lucene Java with 2.9.1 as the version number. Lucene can be used as a part of a search engine as it can perform full text indexing. Lucene Java is, as the name of the application suggests, the release written in Java. For more information, we refer you to this page. The summary announcement of version 2.9.1 looks like this:

Lucene Java 2.9.1 available

This release fixes bugs from 2.9.0, including one serious bug whereby BooleanQuery could silently fail to retrieve certain matching documents.

There are also some minor API changes, including a Version parameter added to QueryParser and contrib Analyzers, so that version dependent defaults are consistent across classes, as well as un-deprecating of certain methods (we were too zealous in a few cases!).

Otherwise the changes are all bug fixes and documentation improvements.

This release is fully compatible with 2.9.0. We strongly recommend upgrading to 2.9.1 if you are using 2.9.0. Furthermore, because some additional APIs were deprecated in 2.9.1, to ensure a clean (“JAR drop in”) upgrade to 3.0 you’ll need to ensure your code compiles against 2.9.1 without deprecation warnings.
