Abstract
A system, computer-readable media, and methods are disclosed for searching a data stream for one or more regular expressions. The method can include receiving a data stream and a regular expression and parsing the regular expression to create a prefix portion and a suffix portion. The method can also include executing a first search of at least a portion of the data stream for the prefix portion using a first search algorithm, the first search algorithm being stored in a computer readable medium and executed by a processor. The method also include executing a second search of at least a portion of the data stream for the suffix portion using a second search algorithm, the second search algorithm being stored in a computer readable medium and executed by a processor. Further, the method includes determining whether the data stream contains the regular expression based on the first search and the second search.
