I realized from the documentation that I'm not looking for
compound words after all, I meant "exact phrase".

I can't see how to make rank tell me which results has an
exact phrase? Like "there must be a occurence of 'new' before
'york'"  (stemmed not really exact phrase)?

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.


Is there something new in rank for pg 8.1?

it has some improving, but not for your case.
