Is it your belief that in the case of asking a question without a clear answer that the quality of the result isn't relevant? Or that all results are of equally high quality? Do you think that the results on the Google SERP are of the highest quality when you ask these questions?
If straight up keyword matching was enough then Google would never have overtaken Alta Vista. Ranking useful high quality information higher is the entire point.
No it isn't. Literally Google's entire initial innovation was a ranking algorithm based on inbound links, weighted by the authority of the linking party. At this point I'm bowing out because you don't even know the basics of the thing you're arguing about.
