Abstract

A method of searching a database uses a plurality of search criteria each having an implicit logical operation associated therewith. After one or more of the search criteria is selected, a computer system with appropriate software formulates the search including the implicit logical operation to search the database, all without the need for the user to input any logical operation connecting the one or more of the selected desired search criterion.
