hi, dear  all, 

I have just read some source code, and found In snort, an implementation of a Aho-Corasick like Boyer-Moore Style Searching Algorthim has given, it allows multiple patterns to be searched for in a packet at the same time.and the snort content rules are placed in a Aho-Corasick like keyword search tree that overlaps similar prefixes.  

best regards

Yes, that's what I'm referring to.
