How do I filter out parts of my sample log and only index a portion of the message for an event?

[DuXa]

I have a log with a long message. i need to cut it from A to B and, if it possible, not to show other events to work faster. Here is an example of my log file.
I need my event from: 81503| main: number of bytes received: 467 to 1| msgsnd_w_retry [dst task: HOST, time: 27/03/2011 09:46:44.0512]: Send msg to queue 34308098. I tried to use LINE_BREAKER, but I could not do it.

Task with ID = 11 is waiting for the message to arrive on the queue 34471943.

Using LINE_BREAKER has nothing to do with it. You need to make your forwarder a Heavy Forwarder and the do the stuff here:
