Hello,
I have a question that arose while using tsearch on a large database
of book information.
In order to inject unstemmed + stemmed versions of searchstrings into
a query we want to cast an expression of type text to tsquery.
Unfortunately
SELECT 'word'::tsquery
(where the literal 'word' is of type 'unknown' seemingly) works just
fine while e.g.
SELECT ('word' || '&fullword')::tsquery
or, simpler
SELECT 'word&fullword'::text::tsquery
gives
ERROR: cannot cast type text to tsearch2.tsquery
How can we work around that? Thanks for any help
Sincerely yours
Alexander Presber
