I have changed in the search preferences to google.com but when I search from the address bar (instant or non-instant) it will still go to google.co.kr. Changing to "Google.com in English" does the same.
The only way is to open google.com first, then do the search in it.
So the question - is there any way to force Chrome to search in google.com instead of google.co.kr? I understand there is some geolocational checking/redirecting, but there must be some way to override it.
