title: wireshark search tcp stream for string
body: <p>I need to be able to search all tcp streams that contain a particular string, not just a particular packet. Something like:</p>
  
  <p>tcp.stream contains "string"</p>
  
  <p>I need to do this in order to filter out all streams containing a certain string to get exactly what I'm looking for. My end goal filter would look something like this:</p>
  
  <p>!(tcp.stream contains "string I do not want")</p>
