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.
Apache Lucene is an open source project available for free download from Apache Jakarta. Please use the links on the left to access Lucene.
Lucene has migrated from Apache's Jakarta project to the top-level. Along with this migration, the source code repository has been converted to Subversion. The migration is in progress with some loose ends. Please stay tuned!
This fixes a few bugs in 1.4.2. See CHANGES.txt for details. Binary and source distributions are available here.
