First reason is to minimize error rather compound it. Second reason is to avoid overloading the user with information. I do expect that the set of queries prepared for a user will be large and possibly imperfectly ranked, at least initially. To use this set in its raw form to pre-fetch answers will dilute accuracy and be a large amount of information. Rather, I take the approach that search is a commodity that is already fast enough and good enough. I let the user choose (and thereby rate/vote up) a query and then fetch only relevant results.
