This is pretty much why I'm still forced to use Google's search engine. Their algorithm is simply just better due to the huge amounts of tracking they're doing. Brave browser's privacy features helps in this case I guess, to prevent cross-site cookies.
Then you might want to use
https://www.startpage.com/. Basically they pay google to use google search result and preserve privacy at same time, best of both world

As with DuckDuckGo, it has the potential. But if I understand correctly, for it to have better and more relevant results, more people need to use it. But then again, not much people use it because the results relevance isn't that good. 🤷
Because their search result isn't personalized and only works well on English language.
I can highly recommend
https://searx.me/ to you.
I have my own personal version of searx hosted at home.
You can configure it to use the search engines you want. It strips off any not relevant data such as browser version, OS, display configuration etc..
If you configure it to use only google, you basically have a google search without any privacy implications.
It only transmit the keyword you searched for and the language for your results to google. Nothing else.
I have mine configured to search roughly 8 search engines and i am pretty happy with the results i get. And no privacy implications at all.
