libplucene-perl 1.25-4 (amd64 binary) in ubuntu disco

 Plucene is a fully-featured and highly customizable search engine toolkit
 based on the Lucene API. (http://jakarta.apache.org/lucene)
 .
 It is not, in and of itself, a functional search engine - you are expected
 to subclass and tie all the pieces together to suit your own needs.
 The synopsis above gives a rough indication of how to use the engine
 in simple cases. See Plucene::Simple for one example of tying it
 all together.
