Sorry, I still wanted to add following link: http://www.sai.msu.su/~megera/postgres/talks/Full-text%20search%20in%20PostgreSQL%20in%20milliseconds-extended-version.pdf On page 6 you can see the first example: "postgres=# explain analyze SELECT docid, ts_rank(text_vector, to_tsquery('english', 'title')) AS rank FROM ti2 WHERE text_vector @@ to_tsquery('english', 'title') ORDER BY text_vector>< plainto_tsquery('english','title') LIMIT 3;" "Limit (cost=20.00..21.65 rows=3 width=282) (actual time=18.376..18.427 rows=3 loops=-> Index Scan using ti2_index on ti2 (cost=20.00..26256.30 rows=47692 width=282) (actual time=18.375..18.425 rows=3 loops=1) Index Cond: (text_vector @@ '''titl'''::tsquery) Order By: (text_vector >< '''titl'''::tsquery)" My PG-version is 9.3. I was wondering about this feature, bacause I haven't seen it yet and it a huge speed up. Sorry, I thought the name is still tsearch, because the functionnames are roughly the same, but now know I noticed, that this name is obsolete.
