I live in a country which uses a language I don’t speak but Google defaults to regional results in spite of my language being set to English. All other engines give me really poor results (not that Google was giving good ones, the image search has really gone to shit since they started populating it with AI stuff).
I use Qwant right now and used it a bit in the past and it’s really bad for my use. I literally always have to swap to Google just to get a result which answers what I check for. :/
I do occasionally swap to Google if I can’t find anything with qwant, but I usually can’t find anything with Google either then.
Maybe your search terms are too broad? Or not broad enough?
