Patent attributes
An information processing method executed by an information processing system that executes processing for searching data to be searched by using a query condition that can be entered via a predetermined user interface and in which individual conditions constituting a query satisfy three properties consisting of reductiveness, idempotence, and commutativity, includes a pre-processing executing step of executing processing prior to processing for searching, and a search processing step of executing processing for searching. The pre-processing executing step includes a query extracting step of extracting a plurality of limited kinds of sub-queries constituting minimum units of queries and satisfying the three properties consisting of the reductiveness, the idempotence, and the commutativity by analyzing a set of statically defined kinds of queries, and a query executing step of executing each of the plurality of kinds of sub-queries extracted in the query extracting step.
