How can I force my browser to search Google in English? [duplicate]

There are two options available for configuration:

which language should Google products use

which language(s) should be used for search results

Open Google Chrome, in address bar type in: http://www.google.com/preferences#languages

You can configure more than 1 language for search results, while only 1 can be set for Google products.

Configure appropriate settings and Save them.

In %LOCALAPPDATA%\Google\Chrome\User Data there is a file Local State which contains the {google:baseURL} information. While temporarily closing Google Chrome, I simply filled in the URL https://www.google.com instead which resolved my problem:
