+ Apache Lucene - Lucene Contrib +

Lucene Contrib +

+ The Lucene Java project also contains a workspace, Lucene Contrib + (formerly known as the Lucene Sandbox), that is open both to all Lucene + Java core committers and to developers whose commit rights are + restricted to the Contrib workspace; these developers are referred to + as "Contrib committers". The Lucene Contrib workspace hosts the + following types of packages: +

Various third party contributions.
+ Contributions with third party dependencies - the Lucene Java core + distribution has no external runtime dependencies. +
+ New ideas that are intended for eventual inclusion into the Lucene + Java core. +

+ Users are free to experiment with the components developed in the + Contrib workspace, but Contrib packages will not necessarily be + maintained, particularly in their current state. The Lucene Java core + backwards compatibility commitments (see + http://wiki.apache.org/lucene-java/BackwardsCompatibility) + do not necessarily extend to the packages in the Contrib workspace. + See the README.txt file for each Contrib package for details. If the + README.txt file does not address its backwards compatibility + commitments, users should assume it does not make any compatibility + commitments. +

+ See Contrib CHANGES for changes included in the current release. +

+ + +

+ You can access the current trunk Contrib repository at + http://svn.apache.org/repos/asf/lucene/dev/trunk/lucene/contrib/. +
