Re: ts_tovector() to_query()

Because the query is what the user is typing in. I don't know what words the user is going to search for. if they
simplysearch for 'Robocop' that would work. But how do I handle the search if they type in more than one word and still
returnhalf way accurate results? 
 

I suppose after talking through it a bit, this may be more of a ranking issue than an actual query issue. I will read
upmore on ranking in the postgres docs. I skimmed past it since it didn't seem to apply, but now looking over it again,
Ithink it could help.
 

Thanks.
Chris

Based on the criteria above, I would say that:
SELECT m.* FROM movies m WHERE to_tsvector(m.item_title) @@ to_tsquery('Robocop')

will do what you need, since "dvd" and "collection" are irrelevant for the results.
