While a fellow Lemmy user dirtfindr examines these search engines, you just could do it yourself: https://peekier.com/ https://swisscows.com/ https://gomu.ca/ https://www.runnaroo.com/ https://private.sh/ https://www.presearch.org/

Peekier, Gomu, and Joshwho are all CloudFlare sites. And if that’s not embarrassing enough, Peekier and Gomu simultaneously claim to be privacy-respecting. So I won’t be looking any further at those two unless something else brings me to them. It’s appalling that they claim to offer privacy while letting the biggest privacy abuser of the web see the queries and all traffic to those sites. Either it’s profound ignorance or it’s intellectual dishonesty.
Runnaroo seems to be garbage.
Swisscows sources from MS Bing and like many engines that do that, they treat Tor users with hostility (just like Qwant and Ecosia).
