It doesn't index stopwords, and it doesn't index the difference between various forms of a word (when the dictionaries reduce them to a common root). > I am concerned a 1mb limit is too low though.

That's pretty much exactly the point: it's not very significant, and it doesn't justify a total inability to index large documents. One thing we could do is index words that are past the limit but not store a position, or perhaps have the convention that the maximum position value means "somewhere past here". regards, tom lane -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches
