MacOS Contacts - Smart List - (Card -- is not Member of -- any Group) --> Doesn't seem to work

I have roughly 1200 Contact Cards. I'm trying to file every Card into one (or more) Groups. I can't find a way to identify the Cards that I have not yet filed. Here's what I tried, using the Smart List feature: Unfortunately, the 'smart' list isn't so smart (or doesn't speak my language). It yields nothing. I'm embarrassed to admit it, but I even tried this, when my first attempt failed. (*Yeah, apparently the programmers at Apple who coded the field 2 options, didn't talk to the programmer who coded the field 3 options??*)
