If you refer to EDI's magnificent spread sheet you will see that you can get almost all of the sites, especially the independent mages, with a level 2 search. I have found that is is a waste of time and resources to do a level 4 search if a level 2 search is performed because the level 3 and level 4 sites are so far and few between that you might go several games before you had a hit with a level 4 search vs a level 2 search. As an aside, if you only did a level 1 search, it is worthwhile to do at least a level 2 search.
