Google also updated their mobile search this week, to provide a “consistent look, feel, and overall user experience” to searching with Google on your computer, stated Reza Ziaei and Mike Buchanan of the Google Mobile Engineering Team.
Using an iPhone or Android device in the US, users can view additional search options that will allow them to refine their search query by tapping a button on the left of the search box on the mobile search results page. They are planning to expand the updates to support additional devices and are working to add more features as well. See an example of the new features provided by the Google team below.
