Google started to go to shit around '08 or '09, allowing their results to be taken over by ad-spammers and a handful of top sites. At the same time, that's about when they adjusted search to make it extremely hard to narrow in on something obscure, even if you know for a fact it's there (this used to be a thing one could reliably do, with some guesswork about word and phrase rarity in the target page and in link text pointing at the target page).
