Almost every search engine on the market is either Google results or Bing results repackaged.

Fun fact: because of legacy contracts, some search engines use results from a Yahoo feed, which in turn are just Bing's results. DuckDuckGo was one of them, they were paying Yahoo, who was paying Bing. The last I checked (3 years ago) they struck a deal with Bing directly.

The company I used to work for would often work out deals where we'd resell search engine results to other search engines too... Very interesting world.
