Comparingthe search results of Yahoo from Google; though Yahoo Search is run by BIng.com; to me Yahoo Search is giving me best results than Google. Google search to me is is so manipulated that the first 10 results sometimes are ads and pertains to go google sites like YouTube and Google+ entries which are not so relevant to what I am looking.
Yahoo Search has been doing great gives you direct resluts and the one that you need. Nothing less. Try it so you will know.
