Best search engines for iPhone not google

There are plenty of choices. DuckDuckGo and Freespoke are two that immediately come to mind. The Brave browser app incorporates its own search engine. There are others.

I accidentally erased all my search engines from my favorites and my SE 3 Apple iPhone13 put them under frekqenly visited and one is missing . Ilm not able to put them back under favorites Forgive me this is all new to me. I will just have to go back to T mobile where I purchased the phone and get them to put them back where the were when the iPhone wasset up.
