I have used SearXNG for a while, but I switched to LibreX after the search engine started glitching. Recently, though, LibreX has stopped returning any results. I am currently on Mojeek, but the results aren't that great.
I have also tried Qwant, but I wasn't too keen on it. Startpage will be impractical, as I use a VPN and this engine often blocks me because of it. I don't want to use Brave Search for a number of reasons. MetaGer has too many important features behind its paywall. I'm not sure about DuckDuckGo, but I could use it if there was no other option.
I recommend Oracle Cloud Always Free - 4 Arm cores, 24GB RAM, 200GB storage. I've used it before they sanctioned Russia and it worked fine (but if hardware fails your data will stay but you will be at the bottom of the queue for replacement)
I used it for a while but could not find good results for any kind of advanced query. Qwant in comparison is slightly better but still worse than duckduckgo unfortunately. For really niche stuff I still need to revert to Google..
