Summary:In one embodiment, a first search operation is performed based on a base lookup word on a first plurality of content-addressable memory entries of an overall plurality of priority-ordered content-addressable memory entries to identify a first matching entry and a corresponding first overall search position of the first matching entry within the overall plurality of priority-ordered content-addressable memory entries. A second search operation is performed based on the base lookup word on a second plurality of content-addressable memory entries of the overall plurality of priority-ordered content-addressable memory entries to identify a second matching entry and a corresponding second overall search position of the second matching entry within the overall plurality of priority-ordered content-addressable memory entries. The corresponding first overall search position is compared to the corresponding second overall search position to determine the overall search result.
