escape? you could just hit delete to clear the text in the spotlight box before you put it away... that way it doesn't search for anythingWait, I figured it out . CMD+Space brings up the Spotlight box. I type in the name of an application that I'm looking for, press enter, and it opens the application. The Spotlight box is still up there in the background searching for anything else related to whatever it is that I typed. CMD+Space to bring up the box, press escape a few times to make the box go away, and mds is down to 0.0%. While it's sort of annoying, I'm glad I figured it out. Surprised nobody else really noticed something like this (or if it's just me).
