What are you getting as a result set? Tsearch2 is highly configurable, but that means you need to use some of the ranking function parameters to get the result you want.

E-mail me, or use the OpenFTS mailing list, which is pretty responsive.

BTW, I’m quoting your blog post for the PostgreSQL home page. I hope that’s OK with you … if not, ping me and I’ll take it down right away.
