Chrome - set search bar to google.co.uk, not google.com?

2018 answer, pulled from Google's docs:

1. On your computer, open Chrome.
2. At the top right, click More More and then Settings.
3. Under "Search engine," click Manage search engines.
4. Find "Other search engines."
   • Add: To the right of "Other search engines," click Add. Fill out the text fields and click Add.
   • Set as default: To the right of the search engine, click More (3 dots) > More and then Make default.
   • Edit: To the right of the search engine, click More (3 dots) > More and then Edit.
   • Delete: To the right of the search engine, click More (3 dots) > More and then Remove from list.

So to add Google UK's search engine, the entry I used had "Google UK" as the Search engine, "google.co.uk" as the keyword, and "https://www.google.co.uk/search?&q=%s" as the URL.

If JNK's answer didn't do the trick, make sure you're using http://www.google.co.uk/#q=%s for the URL. So, the full procedure is:

1. Right click the URL box at the top of any Google Chrome window.
2. Click Edit Search Engines…
3. Click the Add… button.
4. Set the name to whatever you want (e.g. "Google UK").
5. Set the keyword to whatever you want (e.g. "uk").
6. Set the URL to http://www.google.co.uk/#q=%s.
7. Click the Add button.
8. Click the Make Default button.

Go to settings (the wrench on the right)

-> Options

-> Default Search - click "Manage"

-> "Add" button at the top

-> Fill out the info, putting google.co.uk as the keyword

-> You may need to copy the URL from the default google entry.

Enjoy!

None of the answers above worked for me in the latest update of Chrome (October 2018) except the following:

In Chrome under Options (the wrench) go to Default Search -> Manage In the new window fill in the boxes as follows:

Name: Google.XX
Keyword: Google.XX
URL: http://www.google.XX/search?q=%s ** where XX is the specified country, in my case I used .ca for Canada
