How do I add Wikipedia and Google in the search bar in Microsoft Internet Explorer 9?
Where in the settings do I add such custom search engines?
In IE9 the link has changed to 'Find more search providers'
However this link will help you ... It contains both google and wikipedia.

UPDATE: Here is the new link for google.
When you type in your search term in the address bar there should be an option at the bottom of the drop down that appears to add more search engines.
Either manage add-ons\search providers\ or internet options\settings (under the search line, on the general tab)
