Maybe(to add): https://searx.neocities.org

Policies:

• Redirects users directly to a random selection of any known running server after entering query.
• Requires Javascript.
• Excludes servers with user tracking and analytics or are proxied through Cloudflare.

I found this random Searx/SearXNG search engine redirector at https://searx.space under the About tab.

To use it, I save the search redirector as a bookmark at https://searx.neocities.org/#q=%s&category_general=on

I also turn on javascript on at searx.neocities.org because otherwise I have to type in my search query manually into a specific search instance.

However if your threat model requires it, you can also go to the no-javascript version of searx.neocities.org. You will not be automatically redirected to a random Searx instance when using no-JS version.

I type in a keyword in the url bar and then the service redirects me to a random Searx/SearXNG instance. For load balancing purposes, it seems great since no single server will be stressed significantly. The searches are spread across multiple instances.

Sometimes the redirected Searx/SearXNG instances output bad results(e.g. errors). In that case, just use the Searx redirector again to have new random Searx/SearXNG instance.
