Xu,
FTS has nothing with your problem, it's general limitation/feature.

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!
Xu
Regards,
Oleg
