FWIW, there has to be some default results order, so the existing is as good as any.  If Mark decides to include any of the suggestions in this topic, such as an "advanced" search page/box, there will still need to be some default.  Other than boosting Premium groups to the top of the list, I don't think I'd make any other changes for that.  No default behavior will ever meet everyone's expectations though.
