The accessing being based on an index value. The condition test vector including a first plurality of bit values defining the condition relation, a second plurality of bit values defining a key selector, and a third plurality of bit values defining the condition value. The selecting being based on the second plurality of bit values. Each key from the plurality of keys including a combination of bit values representing a portion of a data packet. A result is defined based on the determining.
