It's funny how none of you even question what a search engine should be. Everyone gave in to the concept that you want to find web pages. Wolfram is the first one to say that you need an answer engine. The web has data, you want answers, not necessarily an URL. When you discuss indexing, you imply keyword matching. That has nothing to do with Wolfram Alpha. If anything else, this discussion was a great way to question conventional wisdom.
