How does Search Work?

How Google Search Works? What does Google really think about UI, rankings, data centers, spam, quality raters, quality score, testing, BERT/machine learning, E-A-T, content quality, misinformation, SERP, indexing?

Google is answering these questions on how search works in a new movie:

The movie includes some of the Google employees: Ben Gomes, Jeff Dean, Pandu Nayak, David Bez, Urs Hölzle, Cathy Edwards, Paul Haahr and so many more.
