本源码是AhoCorasick算法实现，它充分利用了词典算法双数组（DoubleArray Trie），既能自己输入指定的多个词进行多模式匹配，也可以将具有指定格式的词典的所有词作为多模式匹配的多个模式-The source code is AhoCorasick algorithm, which make full use of the dictionary algorithm pairs of arrays (DoubleArray Trie), both enter the designated number of their multi-word pattern matching, you can also specify the format of the dictionary will have all the words as a multi-pattern matching multiple modes
