Scoped search definitions can be cumbersome at times and don't really define the business logic of a model. I think hiding them under the carpet by moving most of the definitions to concerns (as we do with hostext) we can later on include would keep the code cleaner. There are 3 or 4 models with just 1 scoped_search attribute I didn't bother to move, later commits that move them into concerns when they become bigger can just ref this issue.
