Prevent Chrome's Google Search from defaulting to the local language / Make English Chrome's Default Langauge

Problem: You're in another country and every time you search for something in Chrome, your Google results are shown in another language (and you want them in English).

Solution:

Settings → Manage Search Engines 

Make ANY other search engine the Default

Click on it to edit the address and insert http://www.google.com/search?q=%s

Click "Done"
