Change default search in chrome URL bar

I have spent half an hour trying to change the default search in the chrome url bar.

The option that worked for me is the following which I found from google.

1. Select Options (Preferences on Mac and Linux; Settings on Chrome OS).
2. Click the Basics tab.
3. Click Manage search engines in the "Search" section.
   • Remove a search engine: Select the search engine from the list and click the x that appears at the end of the row.
   • Add a search engine: Scroll to the bottom of the dialog and fill out the following fields:
     • Add a new search engine: Enter a nickname for the search engine.
     • Keyword: Enter the text shortcut you want to use for the search engine. Use the keyword to do
     • URL: Enter the web address for the search engine.
       1. Go to the search engine you want to add.
       2. Do a search.
       3. Copy and paste the web address of the search results page into the URL field. Keep in mind that the URL for the search results page is different from the website URL. For example, while you'd go to http://www.google.com to access Google, the URL you'd add here is for the search results page, http://www.google.com/search?q=XYZ.
       4. Replace the search term in the URL with %s. To continue the Google search engine example, you'd end up with http://www.google.com/search?q=%s as your final search engine URL. When you type a search in the address bar, %s will automatically be replaced by your search term.

Main issue for me was to delete the search that was not working properly and then re-enter it with correct settings. which for standard google default is http://www.google.com/search?q=%s
