I adore the new look Chrome I got the other day however, when I used the address bar to search for a recipe (as I normally do) it used the yahoo search engine instead of the Google search engine which I prefer. Here is how to fix the issue.
Click the wrench icon on the browser toolbar.
Select Options (Preferences on Mac and Linux; Settings on a Chromebook).
Click the Basics tab and find the “Search” section.
Select the search engine you want to use from the menu. If the search engine you want to use doesn’t appear in the menu, click Manage search engines.
In the Search Engines dialog that appears, select the search engine that you’d like to use from the list.
Click the Make Default button that appears in the row.
you can change the default search engine then.google chrome support
