17016	Empty search not allowed - makes it hard to build an enhanced search page	jobjorn		"Hello all,

I am building an enhanced search form for a recipe database (using a Star Trek LCARS-like interface!). The enhancement is primarily being able to select tags that the returned results should be tagged with. This is made possible in part through using query_posts(); in the landing page, search.php.

However, what if you want to search for *just* tags, and no text? You want to look at what's tagged both ""cheese"" and ""tomato"", and see no need to enter any search term. The result is that {{{$_GET['s']}}} will be empty, and you will not get to search.php at all - and then you can't see your cheese+tomato recipes.

This is because wp-includes/query.php uses {{{!empty}}} rather than {{{isset}}} when trying to figure out whether we want to see a search page attached or not.

Extremely simple diff attached. If this solution is for some reason unacceptable, I would very much appreciate any ideas on how to work around the issue."	enhancement	closed	normal		Template	3.1	normal	wontfix
