Sure, DDG is not quite there, but for most of my queries it's just fine.
Having "deleted" my Facebook account some four years ago was a real liberator, though.
"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 source from Bing, Yahoo, and Yandex."
I use DDG because I like its !bang searches and I genuinely prefer its Instant Answers and page layout over Google's.
Is the web too big for a new search engine company to compete with its own crawler? Or are Google, Bing, Yandex, and Baidu the only search engine companies big enough to crawl the web effectively?
> Bing and Google each spend hundreds of millions of dollars a year crawling and indexing the deep Web. It costs so much that even big companies like Yahoo and Ask are giving up general crawling and indexing. Therefore, it seems silly to compete on crawling and, besides, we do not have the money to do so. Instead, we've focused on building a better search engine by concentrating on what we think are long-term value-adds -- having way more instant answers, way less spam, real privacy and a better overall search experience.
While DDG does use Bing (and others), the DDG searchers are getting the same results because Bing can't track and tailor your results.
Many also like DDG's bang[2] which easily lets you direct your search elsewhere. For example if you search for "example" and don't like the results, then "example !g" sends it to Google. I like it for slightly more obscure stuff - eg "example !homedepot" does what you'd expect. For us python folk, it is nice to do "example !py2" or "example !py3" depending on the codebase.
That said DDG often does get reasonable results. And if you don't like them, just add in !g to see what google gets. (Conceptually I like to give DDG first crack at a search, and then fallback to google if DDG didn't do well.) What I have noticed is google's results are getting worse, as sites are getting better at gaming google.
