Bookmark: A look at search engines with their own indexes by Seirdy.
The three dominant English search engines with their own indexesnote 1 are Google, Bing, and Yandex (GBY). Many alternatives to GBY exist, but almost none of them have their own results; instead, they just source their results from GBY.
With that in mind, I decided to test and catalog all the different indexing search engines I could find. I prioritized breadth over depth, and encourage readers to try the engines out themselves if they’d like more information.
This is one of the best examinations of search engines with their own indexes, which are quite rare. Well worth the read.
