Plucene - Perl port of Lucene http://search.cpan.org/~tmtm/Plucene-1.21/lib/Plucene.pm

Plucene is slow as hell.

You better use Kinoseach, which also uses the same index format as lucene.

Some benchmarks are on this site : http://marvinhumphrey.com/kinosearch/benchmarks.html

Has anyone compare Lucene to Xapian? I have never tried Lucene, but have been very happy with Xapian.

I've heard good things about Lucene, but we use Sphinx: http://www.sphinxsearch.com/ For our tests, it indexed much faster than the common Lucene implementations, and for our needs was also a tad faster overall. I haven't tried the newest version, though.

I don't know what kind of testing you've done but nothing even approaches the speed of Lucene. It's by far the fastest open source search engine currently available. If you're using Rails, I cannot recommend Solr enough. It's amazing. Cutting's a genius.

Do you have references for "nothing even approaches"? Specifically compared to Sphinx? The only comparisons I've found are showing sphinx coming ahead in many indexing/search cases (if only slightly). See my other comment on this thread with links to benchmarks where sphinx clearly "comes close". We did a good bit of research on this, so it does feel odd that you'd say "nothing even approaches".

It was also ridiculously easy to get Sphinx up and going. Lucene is a killer engine, no doubt, but Sphinx's ROI alone won us over.

lucene is pretty cool and it's a lot better than anything I've seen so far (including ferret). The only problem I've experienced with it was index corruption, which is fairly common and frustrating (though in fairness it could have been due to my sys admin skills)
