Pretty minor thing, but would FUZZY capability be better than SEARCH=FUZZY? Somehow I thought there were more SEARCH= capabilities, but I can't seem to find any. And FUZZY isn't really SEARCH-specific anyway, since it works with SORT, THREAD, etc. And that reminds me, should it be possible to return relevancy values also for THREAD? I guess that would require ESORT-like ETHREAD extension.
