NCSA Issues Disclaimer on Google/Yahoo Study

Jean Veronis writes "NCSA has issued a strong disclaimer on the study announced recently on Slashdot that seemed to contradicted the fact that Yahoo's index size would be bigger than Google's: ' Staff at the NCSA noted several issues with the study'. This study conducted by students is 'not an NCSA publication and was not conducted as part of any NCSA project or under the supervision of NCSA'. "
