There's a lot of information on how Google Search Works on our site by that name here: https://www.google.com/search/howsearchworks/ https://www.google.com/search/howsearchworks/ While there's some very short caching of results, to my understanding, there's generally still going to be a lot of hitting the index because there's just a lot of new information coming in all the time. We can't somehow store a set of results for say "cars" and figure it's going to be the same info from one minute to the next. And results don't really have a lot of personalization for individuals. When you see differences, it's usually due to language and location.
