I think I'll stick to tsearch, it seems to work pretty well. I created the words list from one table (2 columns) for fti. 2.6G file and almost 200 million records, and took up almost 8.5G of space in the database. I was going to see if I could do a speed comparison between the two but ran out of space before I could create the indexes on this table. Hmm. Might try it on a different table and see what happens, I'm interested to see the differences (if any) between the results :) -- Postgresql & php tutorials http://www.designmagick.com/
