Depending on the use-case, I find DDG is far better in many cases in returning sane search results. Might be a option to try. Not entirely open-source but better than the GOOG.
Same here, been using DDG for several years now and have not had any issues. I have tried switching to google a few times when im not finding what i need, but get turned off by their recommendations as well as just bad search results. I remember it took be a few weeks to get used DDG when i first switched. In a way it felt like going back to how search used to work, more keyword based, less trying to guess my life story to try to figure out what i really want.
And kagi.com is way better than DDG if you're willing to pay
