> 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.

What this means is that they use 400 sources for things like Instant Answers and other widgets but Yahoo and Bing for all their organic search results.

So its 95% bing/yahoo. I wish they were more transparent. But it does not sound nice when they say do not useevilgoogle instead use our slightly modified bing/yahoo wrapper.

Is it against the ToS of Google to perform search on someone's behalf and relay them the results?
