Abstract
An apparatus, and corresponding method, for performing a search for a match of at least one expression in an input stream is presented. A graph including a number of interconnected nodes is generated. A compiler may assign at least one starting node and at least one ending node. The starting node includes a location table with node position information of an ending node and a sub-string value associated with the ending node. Using the node position information and a string comparison function, intermediate nodes located between the starting and ending nodes may be bypassed. The node bypassing may reduce the number of memory accesses required to read the graph.
