I travel and use VPNs a lot and one very annoying consequence of this is that Google, among other sites systematically redirects all my searches to the local version, which usually ends up being in a language I can't understand, and also different page ratings from the English ones.
It's trivial to solve this by signing in to my Google account (where the language is set to English) or by using another search engine (Chrome in particular). But on Safari the solution has eluded me, because changing the default search engine on Safari only allows you a restricted set of choices of which the default English Google (Google NCR) is not one.
There is a Safari extension called Omnikey which, in theory, allows ne to solve this problem: you can add any number of custom search engines and it will then make this the Safari default. But it requires you to configure a search URL. I have tried https://www.google.com/ncr, https://www.google.com/search?q=%s, but with no luck.
Any suggestions as to what the correct way of doing this might be?
