This message just showed up on the postgresql mailing list. Enjoy.
I'm about to announce a release of OpenFTS search engine.
Short blurb:
OpenFTS (Open Source Full Text Search engine)
is an advanced PostgreSQL-based search engine
that provides online indexing of data and relevance
ranking for database searching. Close integration
with database allows use of metadata to restrict
search results.
This is actually what we use at fts.postgresql.org and
several other sites. Perl version is available for download,
TCL version (with AOL server support) will be available soon -
actually it just needs to wrap a release.
The OpenFTS project web site - http://openfts.sourceforge.net/
OpenFTS team:
Oleg Bartunov - Project Manager
Teodor Sigaev - Principal Developer
Daniel Wickstrom - Developer of TCL Version
Neophytos Demetriou - Documentation Writer
