@bentley_lucas @Tutanota DuckDuckGo is nice, but to my understanding is mostly (or was) a frontend for Bing similar as Startpage is for Google. Do think they have their own crawlers, how much of their results is their own crawlers and Bing don't know. Brave search is probably the biggest independent search engine index, apart from Google and Bing. Why tuta doesn't mention this is because of "reasons" I guess.
