No, it uses Bing AFAIK
"In fact, DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from a variety of partners, including Oath (formerly Yahoo) and Bing."
(Regarding search results + instant answers: https://help.duckduckgo.com/duckduckgo-help-pages/results/so...)
I've asked before, and no one seems to be able to provide me with a source that states that DuckDuckGo is just Bing. Yet it comes up every time DuckDuckGo is mentioned in a positive light.
Saying that Bing is one of hundreds of sources is like saying that PageRank was just one of Google's 200 signals. Or that Google was just one of hundreds during Bing's hiybbprqag brouhaha.
