08, 09 that was the time they introduced service to figure out typos in queries. That was the time that I noticed drastic reduction of usefulness of their search. When the team responsible for it visited my university, I asked about this. Their response was: we don't show results that you asked for, but the results you want.

I goddamn know what I want, and it is so annoying that Google returns sites that don't contain keyword that I explicitly want, doesn't matter that I put + in front or write it in quotes.
