A searchable information database is provided. At least one network processor having one or more packet processors is provided which are programmed to independently search for a match of any one of the keys in a key set which is delivered to the network processor(s). Each key set is independently identifiable and searchable. If a match is found, then either a function associated therewith or a pointer to the location of the information in the database is returned. Several searching techniques can be used. For example, multiple network processors can be used, with each storing the keys of a different set of keys, and each set of keys can be searched concomitantly in the network processors. Alternatively, a large lookup table may distribute multiple network processors. If a single network processor is used, the key sets can be pipeline searched, or pico processors or packet processors can independently search each key set.
