ABSTRACT:
A search apparatus and method for establishing efficiently whether a particular number, eg a MAC address, is stored in a database, eg in a communications bridge. The search is conducted stepwise on the basis of portions of the number, until one or zero match is found in the database. In the event that one match is found, a final confirmation is made that the whole of the number located and the number searched for are the same. This provides an efficient way to search among a subset of possible very large numbers.
