Bing the recently released search engine from Microsoft can be used simultaneously with Google in the same browser window through BingAndGoogle or Bing vs Google web based services. You can compare search results for a certain query in the two rivals engines, Bing and Google.
These sites have a simple and intuitive interface formed by a text area, where you must type the search query (keyword or keyphrase) and a submit button. When you hit the submit button, Bing and Google search engines will be queried simultaneously and the search results will be displayed in two adjacent columns.
The search results listings will be different,Bing will deliver fewer search results than Google.
But this behavior is normal, since Bing was just released by Microsoft and its spiders might still have to work in crawling the web to index more websites.
Bing tends to be an active Google competitor, because new features and functionality are added constantly to it.
