I keep trying to find things like “making waffles from sour dough discard” and all the sites are the same: long meandering paragraphs full of links to other things on the site with dubious instructions.
Considering at this point I can pretty much identify the type of site by looking at it; are there good extensions or search engines which might remove them from search results?
Yes it supports DDG and every major search engine (see: GitHub). You might have to manually give it permission first (like for specific SearXng instances), after which it’ll work.
If you meant can you add DDG as a search shortcut, also yes.
