Completely agree. I really wish there was a way to turn off the presumptions. Usually when I carefully craft a very specific query, I get back a bunch of generic results unless I put in those pluses.

Actually, now that I think about it, this might be something not particularly difficult to solve with greasemonkey...

Edit: Here's my attempt: http://github.com/paulbaumgart/GreasemonkeyScripts/blob/d88d...

Install by clicking the 'raw' link in the top right corner of the script.

Edit 2: Any thoughts on how to make the script run earlier, to avoid making two requests? It seems Greasemonkey doesn't actually support this, so it might have to be its own extension...
