Seems like this should be easy, but I am having a tough time sorting it out.
I am using PE 3.1 and I want to know which of my nodes are missing a certain class. Its pretty easy to get a list of the nodes that have the class in the console, but that still leaves a lot of math for me to do as I have thousands of nodes. The search inventory tool has something close with being able to search via fact presence or absence, but there doesn't seem to be a fact that corresponds to my class. Even if I distributed a fact with my class, that would only report for nodes that actually got the class, whereas I want hits on the fact's absence. Anyone solved this riddle already?
