Abstract: The advent of the World Wide Web made search engines the most essential component of our everyday life. However, the analysis of information provided by current search engines often presents a significant challenge to the client. This is to a large extent because the client has to deal with many alternatives (solutions) described by contradictory criteria, when selecting the most preferable (optimal) solutions. Furthermore, criteria constraints cannot be defined a priori and have to be defined interactively in the process of a dialog of the client with computer. In such situations, construction of the feasible solution set has a fundamental value. In this paper, we propose a new methodology for systematically constructing the feasible solution set for database search. This allows to significantly improving the quality of search results.

Keywords: database search; www search engines; contradictory criteria; criteria constraints; feasible solution set; Pareto optimal set; parameter space investigation method; PSI method; analysis tables; world wide web; internet search.
