Yes.

Where is your evidence for that? It used to be Bing and Yandex, but now it’s just Bing. They use other non search engine APIs and do a small amount of crawling AFAIK. Details of who uses what here: https://seirdy.one/posts/2021/03/10/search-engines-with-own-indexes/

We’d love to build a distributed search engine, but it would be too slow I think. When you send us a query we go and search 8 billion+ pages, and bring back the top 10, 20…up to 1,000 results. For a good service we need to do that in 200ms, and thus one needs to centralise the index. It took years, several iterations and our carefully designed algos & architecture to make something so fast. No doubt Google, Bing, Yandex & Baidu went through similar hoops. Maybe, I’m wrong and/or someone can make it work with our API.
