The current Apache Lucene Java version is 3.6, released in April of 2012. We’ve updated the Lucene 3 tutorial and the accompanying source code to bring it in line with the current API so that it doesn’t use any deprecated methods and my, there are a lot of them. Bob blogged about this tutorial back in February 2011, shortly after Lucene Java rolled over to version 3.0.
Like other 3.x minor releases, Lucene 3.6 introduces performance enhancements, bug fixes, new analyzers, and changes that bring the Lucene API in line with Solr. In addition, Lucene 3.6 anticipates Lucene 4, billed as “the next major backwards-incompatible release.”
Excellent news! Although you will need to hurry reading it. Lucene/Solr 4.0 is just around the corner!
