Thanks for your input. That's only partial search. Once we find that goodbye message (coutn >1) we want to trigger another search which I was referring to in step1. So in essence something like this -
//IF GOODBYE MESSAGE FOUND from first search,
//THEN RUN a second search to harvest certain data for the last 12 hours.
This seem to fit more in subsearch category but we could not get it to work the way we want it to.
