One of the main advantages of Google's new browser, besides fast browsing, is the simple, and uncluttered interface. It is much quicker than IE or Firefox in displaying web pages.
The best aspect is the ability to search and navigate from the address box itself. Just type in a search term in the address bar and you will see search results displayed directly. While Google is the default search engine, you can add more search providers. Let’s take the example of Dogpile. This step-by step guide will teach you how to add this search provider to your browser. (Note: Please click on screenshots to enlarge)

Type the name, for example Dogpile on first blank field. You will also have to type the keyword in the second box and URL with %s in place of query in the third box.

4. There's another easy way to add Dogpile. All you have to do is keep the Basics tab open and open a new tab. Type in www.dogpile.com on the browser address bar and press enter. Now, return to the settings tab and you will see the metasearch engine automatically shows up in the Other Search Engines section. Mouse over and click Make Default.
