I've been banging my head against this for a good hour or so now. How in the world can we do a query where we want to exclude multiple values? I've been able to do ones that match multiple values, but I am at a loss for the inverse. I have carefully re-read the filtering docs. I am trying to make a query that, among other things, excludes multiple serial numbers on /docs/api/#/security/security_certificate_collection_get, and have tried the following:
!SERIAL SERIAL SERIAL
!SERIAL|SERIAL|SERIAL
!SERIAL !SERIAL !SERIAL
Is this even possible, or am I just having a Homer Simpson moment?
