The find() function does not return the correct result, when using a regex, in a Trigger.

Description:
We have a Trigger that uses the find() function.  The Trigger is firing when it should not.

Here is the expression in the Trigger:

find(/VZC EAAA/snmptrap[^\h*trap_oid\h+FNKSBRTR-MIB::funkSbrTrapRealmOutOfService\b],,"regexp","\h+FNKSBRTR-MIB::funkSbrTrapVarFailedSystemName\S*\h+\Wsandvine_test\b")=0

Here is the value in the Log item:
