Identify documents with no tags

[BlueKnight]

New to DevonThink and trying to figure out a way to get information on all documents without any Tags. Sometimes it is just not possible to Tag and would like to go back and tag later time.

I could insert a simple tag (tagme) or something, but it would be great if can see documents without any tags.

Does anyone know of a way to do that?

I have tried this post but this is not working

The post u are reading is to find empty tag (ie tag with no document), not document with no tag.

This one for documents with no tag.

Thank you for the response @ngan, works like a charm.
