Don't be silly. I'm not saying search results aren't important; I'm saying they're not difficult. The specifics of Google's algorithm have to stay secret to make it harder to game them, but the real "secret sauce" is the stuff they don't talk much about: custom built networking switches, smart power grids, and clever software like Map/Reduce. I bet R&D spends a lot more on that stuff than on figuring out how to improve ranking order.
