I'd like a good explanation of how the NOT operation works in CSMARS on keywords search strings. I'm in the process of defining a few new rules in order to exclude events in certain conditions. In other words, I'd like a message to be sent only if certain keywords are not present in the message.
Can this be done? I've already defined a rule that excludes the ACTION when there is at least one of the keywords by using the OR condition. I'd like the message to be sent if the event occurs and the message does not contain "JOHN", "JOE" or "JIM". What's the correct way to proceed in this case?
