Consistent with embodiments of the present invention, a method may be provided comprising receiving a search string corresponding to a desired node comprising a target parameter, a policy parameter, and a class parameter. The target parameter may be referenced with a target index table to determine which interfaces to search. The policy parameter may be referenced with a policy index table to determine a node-id of a policy node corresponding to the policy parameter. A level for the desired node may be determined based on the node-id. The class parameter may be referenced with the determined node-id with a class index table to access a bucket location. The desired node may then be searched for with the determined node-id at the determined level.
