Final (?) search weirdness

[karindalziel]

I made some changes to austen in my latest push to the karin branch. I've almost got the search like I want it, with the following exception: When I search for a phrase, it is defaulting to id (novel) sort, rather than relevancy. It is doing this because I changed the default sort in the application controller. I did that because I want the default sort to be id if there is no word search. There needs to be some mechanism that tells it to default to relevancy sort only if there is also a word search.

Sorry if this is confusing, ask me tomorrow, I just wanted to get it down before I forgot.
