    Abstract
    WWW search engines or surfing tools provide users with catalogues or indexes on the Internet and different ways of searching these catalogues or indexes. There is as yet no standard operation for search tools so that users have to understand the way each one works to use them effectively. Describes, compares and evaluates some of these tools including Infoseek, Lycos, OpenText, WebCrawler, Yahoo!, AltaVista, Inktomi, Excite, Magellan, GAIS, and YAM

    Abstract
    In order to test the power of metadata on information retrieval, an experiment was designed and conducted on a group of 7 graduate students using the Dublin Core as the cataloguing metadata. Results show that, on average, the retrieval error rate is only 2.9 per cent for the MES system (http://140.136.85.194), which utilizes the Dublin Core to describe the documents on the World Wide Web, in contrast to 20.7 per cent for the 7 famous search engines including HOTBOT, GAIS, LYCOS, EXCITE, INFOSEEK, YAHOO, and OCTOPUS. The very low error rate indicates that the users can use the information of the Dublin Core to decide whether to retrieve the documents or not
