A Comparision of the Size of the Yahoo and Google Indices

Anonymous Patron writes A Comparision of the Size of the Yahoo and Google Indices: from Matthew Cheney, Mike Perry, and Dr. Orville Vernon Burton
University of Illinois at Urbana-Champaign and the National Center for Supercomputing Applications. It is the opinion of this study that Yahoo!’s claim to have a web index of over twice as many documents as Google’s index is suspicious. Unless a large number of the documents Yahoo! has indexed are not yet available to its search engine, we find it puzzling that Yahoo!’s search engine consistently returned fewer results than Google.”
