I don't know. I am using DDG from outside the U.S. but with English as the primary search language. The Google's localized results are just an order of magnitude better. I end up re-doing almost 10-20% of my searches in Google after being dissapointed with DDG results. Most of the time Google results are sadly superior. And don't get me even started in searching in my native language (Finnish). DDG is close to useless there, since it can not parse the different, obscure word forms we use (although I type word X in form A, I want my searches to include results in of word X in semantically related forms B and C). Google did not initially parse Finnish very well, but it eventually became amzingly good something like a decade ago.
