As I sit here watching the Djokovic/Federer US Open tennis match I was trying to remember how long the recent record breaking match (length of time) at Wimbledon was. I started my search query on Google with "longest" and Google suggested "longest tennis match" as the second suggestion.

I'm curious how that works. Is it based on other's recent searches? Or is there some sort of a current events algorithm?

Anyway, I'm impressed.
