Actually, this problem also exists for native speakers in their own countries. I'm a German in Germany, yet when I'm searching for technical terms, in the overwhelming majority I want English results because they are better. (The German results are often just blog posts regurgitating what somebody else wrote in English.)
It used to be that I could use www.google.de for German searches, and www.google.com/ncr for English searches, but that does not (reliably) work anymore. I now grudgingly type www.google.com/?hl=en in the address bar more often than not.
