I actually think we should just take it out entirely as far as the search is concerned. I just did a regexp search for `.` in codemirror.js, which is 290K, and it just took a couple of seconds to bring up the panel. Now, trying to do a *replace* on that many items froze up Brackets :) But I think we could just warn at that point ("don't stick beans up your nose") if you try to replace more than, say, 5000 matches, rather than arbitrarily cutting off the initial search.
