Résumé / Abstract

A powers-of-two algorithm is described that automatically creates discrete, well-defined, and unique result sets, displaying them in decreasing order of likely relevance. All computations are transparent, and a simple query form allows the searcher to focus on the choice of terms and their sequence-an implicit indicator of their relative importance. The program can be used with traditional databases or with search engines designed for the Word Wide Web. It also can be used with an intelligent agent to search the Web with a pushdown store, returning only those items that best reflect the searcher's stated interests.
