Yesterday Google released its new version of the search results. They added the ability to drill down on the results. By clicking the plus sign in the top left corner you are given the ability to narrow down the results with search terms. Some of the terms are Images, Videos, Blogs and Past 24 hours. Well they have also enabled this feature on mobile searches.
From and Android phone or an iPhone, when you browse to Google.com you will have the drill down option. By clicking on the arrows on the screen you can drill down your results too. Other phone platforms are in the future for this new feature.
