A relevancy ranking algorithm aims to sort retrieved
information resources so that those most likely to be
relevant are shown flrst. Experimentation reveals that
ranking techniques employed by lnternet search engines
do not facilitate effective retrieval. The methodology
adopted allows for a comparative evaluation of rival
search engines. Additionally, different search techniques
utilised by experiment participants were analysed.
Results show that if more than four search terms are
used,the accuracy of a relevancy ranking will increase.
