convert human searchpattern to postgres-search

I'm just reinventing the wheel and am writing a simple searchparser
that converts human searchinput to a postgres-where-clause.

I'm sure this has been done many times before and maybe there is some
professional module to do this?  Perl would be great, but I didnt find
anything at CPAN.

thnx,
peter
