Check out Argus, <http://www.qosient.com/argus/>.  (I recommend still using 
version 2, version 3 is not quite production quality yet...)

Argus is a stream analyzer, instead of a packet analyzer.  You can search 
argus data by tcp flags, by regular expression on the data (if you enable 
stream data logging, which is optional), or several other options.  See the 
argus site for more information.
