1. An apparatus comprising: a content addressable memory (CAM) array including a plurality of rows of CAM cells for storing a plurality of entries; input circuitry to receive a search key, wherein the search key identifies an initial matching entry in the CAM array during an initial compare operation between the search key and the plurality of entries stored in the CAM array; and a search key generator to generate a first set of modified search keys based on a modification of a portion of the initial matching entry output from the CAM array, wherein the modified search keys identify one or more additional matching entries in the CAM array during subsequent compare operations in the CAM array wherein each entry in the CAM array includes a descriptor field value that is used to generate the modified search keys.
