Hi!
In the source tree of Postgresql you'll find:
postgresql-6.4.2/contrib/fulltextindex
and you'll read README:
---------
The included software is an attempt to add some sort of Full Text Indexing
support to PostgreSQL. I mean by this that we can ask questions like:
Give me all rows that have 'still' and 'nash' in the 'artist'
field.
Ofcourse we can write this as:
select * from cds where artist ~* 'stills' and artist ~* 'nash';
But this does not use any indices, and therefore, if your database
gets very large, it will not have very high performance (the above query
requires at least one sequential scan, it probably takes 2 due to the
self-join).
....
....
---------
I haven't tried, nor I'm sure this is the best solution...
Hope this helps!
