AbstractA 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.
