+Enrico had one that he was using for debtags stuff that looked pretty good.
+That was [Xapian](http://www.xapian.org/), which has perl bindings in
+libsearch-xapian-perl. The nice thing about xapian is that it does a ranked
+search so it understands what words are most important in a search. (So

 >> I've done a bit of prototyping on this. The current hip search library is [Lucene](http://lucene.apache.org/java/docs/). There's a Perl port called [Plucene](http://search.cpan.org/~tmtm/Plucene-1.25/). Given that it's already packaged, as `libplucene-perl`, I assumed it would be a good starting point. I've written a **very rough** patch against `IkiWiki/Plugin/search.pm` to handle the indexing side (there's no facility to view the results yet, although I have a command-line interface working). That's below, and should apply to SVN trunk.
