Hello, I apologize for my stupidity, but I have a problem with the minus subtraction tag.

I have two tags across the space key:

"unknown_artist"
"artist_request"

If I write them together, and add subtraction (minus) to one of them, the first tag also disappears in the search if the image contains both of these tags.
How can I make an image that contains both of these tags disappear only when a subtraction (minus) is added to all image tags?

Forgive my bad English or if I missed posts with similar problems.... I'm not a good reader

Put a minus before every tag you want deleted from your search:

all_the_tags_you_want -unwanted_tag1 -unwanted_tag2

...and so on.
