Is your feature request related to a problem? Please describe.
For example, in a recipe site that contains 2000 articles (recipes) I set the "video" tag in recipes that contain the video recipe.
If I wanted to search for all the recipes that do not contain the "video" tag to understand which items I have yet to integrate the video at this moment it is not possible.
Describe the solution you'd like
In the list of items, have a field next to the Tags one that allows me to search for items that do not have that specific Tag inserted.
