Thread: free form text database?

I'd like to build something where I can store a searchable database of
free form text.
Right now I'd like to input usenet articles in a similar fashion to
Dejanews but only with
the groups I am interested in.

There use to be a shareware program called WAIS that would have been
similar to
what I was thinking of but it appears to have died off. Could Postgresql
be adapted
to this?

I've done something similar with a Perl cgi script but it's dead slow
and not very
expandable. What I'm looking for is a database of all words pointing
back to the
articles that contain them.
