I'm pretty sure Bing still makes up a large portion of their results. I remember reading some official stats at some point that their own crawler was such a miniscule part of the results that in effect you were just basically using a more limited version of Bing.

I've been using duckduckgo for several years and unless Bing had radically changed in recent times, I would consider Bing to be the more limited of the two.

I wanted to look up a translation and tried !wr word on bing and it did not load the wordreference.com page for word

I wanted to find a pizza for tonight and I'm not familiar with my current location, so I typed pizza near me in bing and it returned results for pizza chain store in US, Canada and India while I'm in western Europe. Same search in duckduckgo gives me an openstreetmap based map centered on my location with addresses of places to get pizza and yelp reviews.

I could go on for a while with other examples showing that duckduckgo is definitely not a limited version of Bing.

Thanks. I would like to see numbers on how many of the search results actually come from their own crawler though. I may be wrong but it feels like most of them come from Bing or Yahoo.

and yandex.
