I think that’s an oversimplification. I get different results.
Wiki claims (with five sources I didn’t check):
DuckDuckGo's results are a compilation of "over 400" sources according to itself, including Bing, Yahoo! Search BOSS, Wolfram Alpha, Yandex, and its own web crawler (the DuckDuckBot); but none from Google.
Last time I did a comparison, I got identical results from DDG and Bing run in sandboxed browsers.
