Really, this thread just looks like a bunch of paranoid conspiracy nuts, thinking Apple is out to steal your searches. I get it, privacy is important. I don't disagree. But you're* acting like they installed a keylogger on your computer (in point of fact, someone on IRC accused Apple of making "something that sends all of their local query keystrokes to Apple", which is a pure fabrication).
* that's the plural "you", not you personally
By the way, there's a perfectly good English word that means "plural you minus you personally," which is "they."

If I was talking to you personally, one-on-one, I'd use "they". I used "you" because I was speaking to the larger audience of the people involved in this thread.
Based on the consistency of the delay, I assumed it was doing the quick local search for the top hit, and then deferring the more expensive searches (including internet-enabled searches) until it's decided that it's time to show the results window. So I tested it, sniffing http traffic, and while I didn't pinpoint which particular queries are sent by Spotlight, there was reliably a burst of HTTP traffic right before the results window was shown every time, and no noticeable HTTP traffic before then. This suggests that my assumption is correct, that it's not doing the internet-enabled search until it believes that the user is done typing.
Based on this, if you type your search and hit return immediately, then it won't have sent your query anywhere.
