The query I'm executing has a GROUP BY clause and because I'm using the headline function I need my tsquery object in the SELECT clause and therefor also in the GROUP BY clause. BUT when executing the query I get the following error. -> "could not identify an ordering operator for type tsquery"

Which version do you use? Only 8.2 will have comparison operator for tsquery.
I'm using 8.1.4 at the moment but I guess I need to update. The 8.2 is looking really promising. So with 8.2 I don't need the subselect?

How do I solve this?
Use subselect:
SELECT *, headline(..., to_tsquery()) FROM
{
	SELECT .... GROUP BY ...
);
Thanks I'll try it.

BTW, for performance reason, it might be useful to use limit in inner select -
headline function is slow enough.
You think?! ;)
Thanks again for your quick reply.
Cheers, Henrik
