Use ~*'^basic'

It will use the indexes I believe. Also, enable likeplanning (look in
contrib/likeplanning) -- it will speed things up too.. If that doesn't help
then use EXPLAIN to get your query plan and post it, I'll try to help
further... I'm doing this exact thing, so have some experience on tweaking
it (Thanks again Tom!) :-)

I'd bet what's happening is you're doing a seq scan, not something you want
to do on that big of a table. (I know that's what's happening with using
~*'whatever' )

Make good use of the stop words in fti.c too (be sure to order them, it's a
binary search).

Hope that helps..
