Freshdocs is incredible. A lot of people are stuck in the old mental model where Google released a new index every month.

That's actually super impressive. So there's basically no "index" anymore, in the sense that the results returned are almost "dynamically" generated? And I'd guess that all of that still needs to be pretty cheap, computationally speaking.

I've seen this before - I've complained on HN that google has no results for X, and within two hours google's first(and only result) was the very thread of me complaining about it.
