Found a few pages about search engines, you might like these as well:
Search engine map displays the largest English language search pages:
https://www.searchenginemap.com/
It is inspired by the map of the internet and displays search engines and their indexes. Because only a few search engines crawl the web themselves. Most use other indexes.
The largest are Google and Bing (for example duckduckgo and ecosia use bing as their index).

Enjoy!
