I'd first try to just issue a seperate query for each of your special terms (ANDed with the original query), and take it's result count. Ideally you wouldn't use find_by_contents for this (because it fetches results from the db, which you don't want here), but use something like VoObject.ferret_index.search(query + " AND cat",...).total_hits Jens -- webit!
