Best alternative search engine option that actually works?

> I find no search engine works well for everything so I just add multiple search engines to my browser so I can quickly and easily use whichever search engine I’d like by using shortcuts. If your browser doesn’t support that functionality you can use DuckDuckGo bangs or Brave bangs instead. Usually DuckDuckGo works fine but sometimes I’ll need to check Brave Search or Google instead. This seems like an interesting option to me but I don’t know how I’d do it or which search engines would be best for what purposes. Or what “bangs” are. I currently use Firefox with all the AI features turned off. (I am really, really bad at remembering keyboard shortcuts. I literally have dozens of the most common ones printed out and taped to my laptop next to the built in trackpad.)
