Contrary to SearX/SearXNG, you can't select more than one source for your search results. I honestly don't see the point in this case. Just use DDG, unless you don't want to use Yandex/Marginalia/wiby directly? The other sources included are DDG, Brave and Mojeek, but those already respect your privacy.
No, Google's not in there, but then again so what? I've had to disable Google as a source for SearXNG because it was systematically returning garbage results.
With 4get you can set a different source for your web searches, pics and news results, however. That's a good feature.
It's opt-in.
