Tried the Qwant privacy-oriented search engine, but it's much weaker than Google. It couldn't find my own web page or maps to local buildings.
@peterdrake the number of search engines that maintain their own indexes is small but interesting. This article pretty comprehensively covers the options: https://seirdy.one/posts/2021/03/10/search-engines-with-own-indexes/
The trick, I think, is to use them in different situations than you would one of the big engines. For instance, I really enjoy using https://search.marginalia.nu/ at those times when I search for some device hoping to find interesting ways people are using it and DDG just gives me product reviews.
@peterdrake yeah I like the concept but Google has set the bar really high.
@peterdrake Qwant is in large part just a front end to Bing, similar to DuckDuckGo. Your failed searches surprise me. I wonder if it's because they optimize things for France?
