I had been using Duckduckgo but I've been dissatisfied with tweaking the results. For instance, turning off the localization in the settings did not remove (commercial) results in my native language even when searching keywords in english.
I switched to SearxNG; I found a local instance. Very satisfied for the moment, I recommend testing it!
this is a great search engine, thanks for sharing the info on it! I found a Firefox extension to replace the built in browser search with SearxNG, the only downside is I'm not sure how to add different instances using the extension.
