Right now I use Searx as my main and DuckDuckGo as a backup in case my main engine fails me. I can’t recommend Startpage to anyone since, despite being privacy-respecting, uses only results from Google, so it cannot do anything to prevent censorship.
Use metasearch engines that aggregate results from multiple engines such as Bing, Yandex, Wikipedia, etc. Don’t rely on a search engine that gets it’s results form only one engine (such as Google or Bing).
YaCy is a good alternative to Searx which makes it even harder to censor the web. MetaGer and Ecosia only use Bing results (MetaGer also uses another search engine but it’s pretty bad and can be disabled). Jive Search is still new but has a lot of potential. SwissCows (the most private search engine that somehow didn’t meet privacytools.io criteria) would be good if it didn’t filter swear words.
