Allow methods of up to 12 lines

I agree that 10 lines is a good guideline but it seems a bit much to
strictly enforce it, and in this particular case I don't think it would
aid comprehensibility of the method to refactor it to move part of the
literal data structure describing search parameters out somewhere else
just to satisfy the 10 line limit.
