They use statistical sampling to make sense of all those results, to see which types of results are most pleasing to their users.
Statistical sampling of what? All I can think of here is "user metrics", but as we've discussed elsewhere, they have pretty limited access to those. How else can they measure how pleased searchers are?
I'm thinking of the announcement that people were searching more than ever, therefore recent tweaks were a success, and how we all immediately read it differently: more searches could mean people aren't finding what they want.
