I have two namespaces that I want to compare data from. The first is ab\*:cd.blah1 and second is ab\*:cd.blah2 and each contain a reference ID for a transaction in the same field name.

I want to return values in ab\*:cd.blah2 where the reference ID does not exist in ab\*:cd.blah1 and both have filters applied to them. Is this possible to do within the Kibana interface?
