I mention it from time to time, but in the spirit of "If the product is free, you are the product", there's a paid search engine called
https://kagi.com/ that has no ads, no tracking and a whole bunch of nice features. Produced by some clever Serbians and growing by inches. People rely on search so much day to day, I honestly think it's worth a few quid a month to get something other than Bing or Google.
I've never looked at SearX and maybe I should, but honestly I think something like a search engine - to be both good and private - needs money. It's like that old NASA joke but with privacy, quality and free: "Pick two".
