I don't know whether you'll run into the other need I had that required some special handling for full text search with legal documents: things like dates, case numbers, and statute cites were not handled well by default. What I did there was to pick those out with regular expression searches, put them into a space-separated string, cast that to tsvector, assign a higher weight to such key elements, and concatenate that tsvector with the one generated from the standard text parser and dictionaries. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
