Using the full text function to run a search stunt on a table. all seem working fine except im looking for ways to fine tune the table relevance. i found out that the function relevates a row higer by the number of keywords found in it and not by if all keywords is present in the row... for instance, if i run a full text search of "foo bar" against a table like the simulated one below:
title | Comment --------+-------------------- row a | bar bar bar row b | foo bar row a will be relevated against row b probably coz bar occurs thrice. how can i fine tune the search so that it relevates according to the precense of keywords.
