Abstract
A search-routing database is used to direct database search requests to only those databases that may contain results to the search request. The search-routing database contains a subset of the data fields from the other databases in the network, along with a field indicating the database to which the search request should be routed. When a database search request is received, a modified search request is generated based on the overlap between the type of information contained in the search request and the type of information contained in the data-fields of the search routing database. This modified search request is submitted to the search-routing database, which returns a list of database candidates which could produce results to the original search request. The original search request is then submitted to those database candidates, and the results are returned to the user.
