Google is typically tight-lipped about it the inner workings of its search business, but there are a few nuggets worth looking at in a Popular Mechanics interview with Udi Manber, the Google vice president who oversees search quality. Among them: Google rejiggered its search algorithm 450 times last year.
The job of the algorithm is to best match Web pages with people's search terms. One tweak the company tried last week was increasing the "diversity" of search results so the listed Web pages would cover a broader scope in an attempt to compensate for the ambiguities of search terms, he said.
