Isn’t the real problem “I have 300 notes that could have up to 50 tags each, and I want to know which tags have not been assigned to this note”?

I have 50 tags and 300 notes; each note has 2-4 tags. I realised it wasn’t clearly explained when I saw the reply you refer to. Sorry about that.
The use case is not far from the one stated here, exception made of the “cluster”:

@mwra

So you’ve reviewed 500 papers and added added multiple values (tags, keywords, whatever) to each item, indeed possibly several different attributes on different aspects of the work. now, you want to get a feel for which terms cluster together.
