Thread: Results in ERROR: syntax error in tsquery:
Dear All,
I have a ts_vector column in question table called weighted_tsv.
I am trying to search using ts_query as follows
SELECT *
FROM question
WHERE weighted_tsv @@ to_tsquery('Hur ofta');
But the query results in an error as follows:
ERROR: function ts_query(unknown) does not exist
LINE 1: ...* from question where weighted_tsv @@ ts_query('...
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
What is the reason I am getting this error I am not able to figure it out.
It would be of great help if anyone point me into right direction.
Thanks
Kiran

Hi,
Thanks for the reply. It worked.
But I also fixed the original ts_query as follows which gives the exact result
SELECT * from question
where
weighted_tsv @@ to_tsquery('Hur&ofta');
Thank you .
regards
Kiran
