Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It is suitable for nearly any application that requires full-text search, especially cross-platform. License: The Apache License 2.0 Changes: This version contains fixes for serious bugs in 2.3.0 that could cause index corruptions in autoCommit=false mode or in cases where multiple threads are adding documents where some have term-vector enabled fields and some don't. The autoCommit option was added to IndexWriter with release 2.2.0. If not explicitly set to false, the IndexWriter runs in autoCommit=true mode. This version does not contain any new features, API or file format changes, which makes it fully compatible to 2.3.0.
