"There is little difference between personalization and the relevance of search results. How would you go about ranking then? alphabetically?!"
Oh, you know, maybe using Google's much vaunted "PageRank" algorithm, which is supposed to take in to account things such as links on other pages back to the page being considered for inclusion in the search results.. the more such links there are, the better the rank is supposed to be.
The above description is obviously an oversimplification, and I don't have access to Google's PageRank algorithm anyway, so couldn't tell you what it actually was if I wanted to, but it's something along those lines, and need not take in to account your previous search history in any way or "personalize" the search for you.
