The current invention provides a system and method for queuing and distributing requests to one or more query servers. The system contains a first tier queue associated with a server based mechanism for directing service requests to a second tier queue associated with each of the one or more query servers. The current invention provides a "pull" model for the distribution of an initial service request of a query containing two or more service requests. Subsequent service requests from this query are assigned to a query server without being placed in a first tier queue. These subsequent service requests are placed directly in the queue of the query server that handled the previous service request from the same query.
