So I've tried out a few search engines but no matter where I look I can't find a great answer.

• Qwant was decent for a bit but as I eventually found out they don't use their own index.
• SearXNG, same as above.
• Mojeek was one of the first I went with but I often can't find what I'm looking for when using it.
• Wikipedia gives me YaCy, Exalead, Opensearch, Gigablast, and Elasticsearch but either I can't find the URL's for them or they require I install something on my computer.

What did you all end up picking? And does it even matter if the back-end is American owned, do American companies make money from that (or does that give them inordinate control)?
