SearxNG Open source metasearch engine that gets results from over 70 search engines. only thing i don't like about it is the "Engines cannot retrieve results" error you get sometimes, but other than that its pretty good. 4get Privacy respecting and lightweight metasearch engine that doesn't suck [ 1 ]. You can choose which search engine to get results from, one neat thing about it is it doesn't require JS for it to be usable. They also have an onion domain...
