Abstract
A content search system includes multiple pipelined search engines that implement different portions of a regular expression search operations. For some embodiments, the search pipeline includes a DFA engine, an NFA engine, and a token stitcher that combines partial match results generated by the DFA and NFA engines in a manner that prevents either engine from becoming a bottleneck. In addition, the token stitcher can be configured to implement unbounded sub-expressions without utilizing resources of the DFA or NFA engines.
