I am having the same issue with "$". Specifically, I'm trying to create a rule that shows all user accounts enabled but want to filter out workstations - which always end with "$". The example below, regardless of how I set the condition operator, returns both workstations and actual users.
On a related note, are there any other condition operators available besides "equal to" and "not equal to"? The documentation seems to suggest so, but when I create the search, I can only toggle between "equal to" and "not equal to". Thanks.
