[bug 1100394] Implement simple_query_search in Advanced Search.

This was pretty easy. I still need to decide where the documentation should go. I kind of think it should be a KB article linked right from an (?)icon to the right of the search box.

Anyway, r?.

It creates one, then the other. The way the Analyzer code works is the analyzer stuff gets added/edited afterwards with `query = es_utils.es_query_with_analyzer(query, language)`.
