Abstract: A method and system for searching the World Wide Web through a sub-root domain name agent connected to a proprietary URL within a hierarchical directory system are provided. Sub-root domain name agents are keywords or combinations of words connected as a prefix to a proprietary URL, continuously linked together in a hierarchical chain that interfaces with a searchable index directory. Within the hierarchy, sub-root domain name agents direct the user to either a hub site for refining the search or directly to a proprietary Web site.
