SELECT idxw, (ts_rank_cd(to_tsvector('spanish', textow), q)) AS rank
FROM word, to_tsquery('amenazar & estructurar') q
WHERE to_tsvector('spanish', textow) @@ q
ORDER BY rank DESC

Y SI SE USA LIMIT
SELECT idxw, (ts_rank_cd(to_tsvector('spanish', textow), q)) AS rank
FROM word, to_tsquery('amenazar & estructurar') q
WHERE to_tsvector('spanish', textow) @@ q
ORDER BY rank DESC
LIMIT 1
----------------------------------------
2680;0.75423
