One day i was searching some keywords with google, i found result as usual, suddenly i thought may be i can get some better result in Yahoo too. Then i opened a new browser and searched same. It was good to me. i got my desired result in both of the search engine and they were different. When i dig more about it i found these links which was really wonderful. This link was
http://www.gahooyoogle.com and http://www.jux2.com
Gahooyoogle is opening Yahoo and Google both engines within a single browser and jux2 is opening 4 tab for "Best Result", "Yahoo Result", "Google Result" and "MSN Result" so any one can easily compare search in these super search engines.These links are really very good and useful.
