Perl port of the Lucene search engine
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.
