I know you are saying it tongue-in-cheek, but you still need to have a decent amount of knowledge of the domain in order to craft a good query and be able to separate the wheat from the chaff.
In some limit cases, that's true, but I've literally heard the following two questions asked in the last week (one directly to me, one in the same room I was in; these are not FoF cases):
What is SCOM?
What is MRTG?
In both cases, knowing nothing about the domain gets you exactly the answer you want. I think far more often than it doesn't, a relatively naive query to Google with a followup query or two with certain words excluded will get you what you need.
