Well for one, results come from far more sources than /just/ bing and yahoo, and they are also put through a custom algorithm. Then there is the 0-click info, official sites, etc. As for building an index, I'm not sure what the plans are there, however there has been some discussion of a distributed spider. Obviously, spidering would mean a LOT of resources directed away from search (don't forget the limited human resources too).
