Neither Mojeek, a British search engine, nor Duckduckgo, Russian, track your keywords, everyone gets the same results
The other search engines, record your keywords, tailors the results from previous searches and adds paid results and adverts etc..
The Star uses Wolfram, an answer engine. Unlike a search engine it uses various logic arguments to solve problems, so searching for sex will provide meaning but no links to porn sites.
