Phrase search
This tip is by Mike Rylander
To do phrase searching just add an additional WHERE clause to your query:
SELECT id FROM tab WHERE ts_idx_col @@ to_tsquery('history&lesson')
AND text_col ~* '.*history\\s+lesson.*';
The full-text index will still be used, and the regex will be used to
prune the results afterwards.
