There is a lot of technical details about how it’s built on the tech blog: https://0x65.dev/
(Disclaimer: I work at Cliqz)
1. Search for a blog I follow
2. Look at the snippet for the blog's homepage
3. Figure out how long ago the page must have been crawled to get such an old snippet
I only tried a few, but they were months to years out of date.
edit : my bad, actually they do use Bing in addition to their own crawler
And DuckDuckGo.
> To do that, 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 multiple partners, though most commonly from Bing (and none from Google).
Do you view that as misleading/incorrect?
That fits well with what GP claimed.
