Title

Search engine showdown : IW Labs tests seven Internet search tools

Abstract

Reports results of the IW Labs tests carried out on 7 major WWW search engines available free of charge on the Internet: AltaVista; Excite; InfoSeek; Lycos; Open Text; Web Crawler; and WWW Worm. Notes the differences between these 7 search engines and the Net directories like Yahoo and Magellan, which are essentially registries of web sites based on descriptions submitted by webmasters or written by the directory's staff. The search engines were tested using both simple searches for the name of a celebrity or a popular web site as well as more complex searches. Results indicated that the most relevant results and the most comprehensive results were obtained from InfoSeek and from AltaVista respectively. Excite was almost as good as InfoSeek in finding relavant pages and users who are comfortable with Boolean searching may prefer OpenText, which excels in this respect
