Is there anyway to find an item that does not have a tag?

I want to find items that are untagged. Any tips on how to proceed?

You can search for item:!tagged or use Item is not Tagged in a smart group.

Is " ! " The search modifier to signify “not”

How long do you think that it would take to tag 5000 files. The files are stored in iCloud but also reside on my System Disk SSD.


Not long generally speaking but the context of your question is unclear.
