I think you'll need to make it stateful.
I assume this is meant to be used for things like catching references
to "Falun Gong" in SMTP sessions and stuff like that. Not that I know

Anyways, if the string goes across the TCP data portion of multiple
packets, statefulness becomes necessary to catch it. Right?
