A string matching system is described herein that provides for very fast and efficient pattern matching against large sets of certain types of pattern strings. If a set of pattern strings is comprised of strings that can be logically divided into segments, these pattern strings can be stored efficiently in a tree-like data structure, segment by segment, storing pattern-match syntax segments separately from literal string segments.
