Here are the two values I want to be equivalent.
cell=DEV-B-Cell, node=DEV-B-Node1, server=server-b-node1 cell=UAT-A-Cell, node=UAT-A-Node1, server=server1-a-node1
I have the following two filters:
([Nn]ode|[Nn]ode) replace nodeX (server-b-node1|server1-a-node1) replace server1-node1
I found this caused the second filter to fail because "node1" does not match "nodeX". By changing the second filter, I was able to have the second filter trigger.
This exercise raised the question of the order filters in a filter-set execute. The Custom Compare dialog displays the filters in alphabetical order of the description. In order to display and/or change the order of filter application, I suspect one would load the filter into the Compare Filter editor and expand the filter-set of interest.
If any changes are made to the filter set, the filter file must be saved and the custom compare re-executed using the filter-set.
