If you want to find only combinations of words that are close one to another,
with the patch you could use something as:
WITH a AS (SELECT to_tsvector('a b c d e g h i j k') AS vec, to_tsquery('a&d')
AS query)
SELECT * FROM a WHERE vec @@ query AND ts_rank_cd(3,vec,query)>0;
I could not find another way to make this type of queries. If there is an
alternative, I am open to suggestions
Best regards
