I have, and it has never been good for my purposes. In English, I just can't find things I need, in Russian, I find things I wish to never see again, tbh.
What is your experience with it?
Edit: The best search for my purposes historically has been on Pinterest. Unfortunately, not anymore. I normally search for visual artifacts (photos, art, schematics, etc), out of all search engines Google is still the only one that is somewhat functional for me in this regard.
I tried DDG, Kagi, Yandex. None of them worked for me.
