Hello,

try the query:

SELECT s, ts_rank(vector, query) AS rank
FROM t, to_tsvector(s) vector, to_tsquery('hello') query
WHERE query @@ vector;
      s      |   rank
-------------+-----------
 hello       | 0.0607927
 hello world | 0.0303964
(2 rows)

Sorry, the query is:

SELECT s, ts_rank(vector, query, 2) AS rank
FROM t, to_tsvector(s) vector, to_tsquery('hello') query
WHERE query @@ vector;
