But if I want to query just part of the string return set is empty:
SELECT * FROM clients
WHERE to_tsvector('english',name) @@ to_tsquery( 'english','somes');
returns no results.
Is it that postgresql doesn't support substring queries or have I missed
something. I can not find anything on the net. Postgresql is v8.3.1.
Um - you're using the full-text indexing. It's supposed to search words.
You can use any of the pattern-matching functions / operators (LIKE etc)
here if you want to explicitly match characters.

If that's not what you're after, you'll need to explain what you are
trying to do.
