I am not an expert on FTS, but I have been reading and experimenting. Further, I don't know what you are really attempting. With those warnings behind us, I think a GIN or GiST index are helpful in full text searches.

I suggest that you review the Postgres Documentation for FTS:

One option you may find interesting is the pg_trgm module:
