hum ... 'quick' search is _not_ a strict search, and I don't think I want that.
To answer your question, yes, it's possible, but I think it would wreck havoc. I already foresee people complaining the search doesn't work anymore

.
Besides, searching for 'tommy' stops at 'handle' level since there are results. Again, searching by real name happens ONLY if, when searching for a handle, no result show up, then no result show up for 'ex-handle' either.
really, I think in these cases, you should use the 'full' search and tick the 'exact' box.
