Hi, everyone:

First I can successful run this query:
select name, ts_rank_cd(vectors, query) as rank from element, to_tsquery('item') query where query @@ vectors order by rank desc;
But actually I want to run this one:
select name, ts_rank_cd(vectors, query) as rank from element, 'item'::tsquery query where query @@ vectors order by rank desc;
Looks like that FTS does not support directly use "::tsquery " in such query. Do I misunderstand something?  Thanks!
