Search engines compared

Mixed in here are search engines and metasearch engines. Metasearch engines like DDG, Metager, and Searx are not actual search engines but rather sites that query other engines. I would rather see only actual search engines for comparison. I would like to see some non western (search engines based in non NATO aligned) countries included such as Yandex.

Data collection always happens. How does the engine know what to return if you did not send it a query(data)? Sometimes results are personalized/manipulated. Anonymity reduces impact of both.
