Probably, Google is the most advanced technology on Earth.
They built their Operating System (OS) for data storage.
They have “seen” a lot of queries and people interacting with their pages so they can build on that experience.
They don’t have a “single” algorithm, but multiple, competing algorithms.
They store quite a bit of the Internet on hard drives and can search through results in less than a second.
They have a business made so that they can get money out of ads.
Also, working with sensitive date is not easy.
