Abstract

A method and system for facilitating a keyword search request initiated at a client station within a multilevel data network, wherein the multilevel data network includes multiple local sites each containing multiple data pages. Multiple keywords from each of the data pages within the local sites of the multilevel data network are stored locally and indexed such that each of the keywords points to one or more of the data pages in which the keywords are contained. The keywords and their index associations are locally updated. A central database is utilized to compile and index the locally indexed keywords from each of the local sites, such that each of the keywords in the central database points to one or more local sites from which those keywords came in response to a keyword search initiated at the client station.
