WebCompile the standard Aho-Corasick automaton into a deterministic finite automaton (DFA). When this is disabled (which is the default), then a non-deterministic finite automaton (NFA) is used instead. The main benefit to a DFA is that it can execute searches more quickly than a NFA (perhaps 2-4 times as fast). WebToday: Aho-Corasick Automata A fast data structure for string matching.
