Here is a web page with a list of search engines.

Google is the go to engine that governments ask for help when attempting to shut down access to a particular website.

Having a list of alternative search engines is good. It would be even better if we had an ip address for each of these.

Note some of these engines rely upon other engines to operate. So, if a relied upon engine decides to no longer list a website, any other engine using it will have the same results.
