I’m wondering if it would be possible to, for example, return only search results that have two or more tags in common with the current file.
Things I have tried
Went to the Dataview site and tried several things (shots in the dark, I had no idea what I was doing) but none of them worked. Tried for example adding the matching tags criteria twice with an AND between them, tried various ways of writing it as an expression by putting >1 or >=2 in various places. But this was all uneducated guessing.
