  • executing a search of the database for each of a plurality of rule sets, each of the rule sets specifying constraints that define a scope of the catalog data comprising one of the custom catalogs, and each of the rule sets uniquely identified by a rule set identifier, said executing a search performed in accordance with constraints specified by the rule set and returning a set of search results in the form of a subset of the catalog data having the scope defined by the constraints;

    associating each set of search results with the identifier of the rule set used to generate them; and

    responding to a database query, the query specifying constraints defining a scope of the catalog data and being associated with a rule set identifier, wherein said responding further comprises;

    executing a search of the database in accordance with the query constraints, the search returning a set of query results in the form of a subset of the catalog data having the scope defined by the query constraints; and
