How to exclude cards with a tag?

[Greg Reagle]

Hello. I am using Mnemosyne with pipx:
package mnemosyne-proj 2.11.0.2, installed using Python 3.11.2

How do I exclude cards based on their tags? This would be equivalent to a logical AND NOT or a set theory SET DIFFERENCE.

For example, I am studying cards with tags A or B or C, and I come across a card that I find annoying and I want to forget about or suspend. I want to be able to add tag X and filter equivalent to:
(A OR B OR C) AND NOT X
(A UNION B UNION C) MINUS X

This could be for leeches, or for information that I just find annoying, or cards that are low priority when I am very busy.

I know that I could remove tags A, B, and C for the card in question, but this has some significant disadvantages. I permanently lose the information that was conveyed by the presence of tags A, B, and C. To get it back into rotation in the future, I have to re-add all three tags A, B, and C, instead of the much more convenient deleting just tag X.

I am using some logic and set "algebra" here for clarity, for those who understand it. I am not insinuating that the interface needs to use these mathematical concepts directly.

I'm afraid this is not supported at the moment, sorry...

Perhaps you could use a Python script to add special tags to all the cards you want. As an example, I've attached a simple Python script that you can modify as needed. 

However, writing such a script might require some Python skills. But I believe it's easy to learn, and I encourage you to give it a try.

Thank you to both Peter and matthewD for your answers. Given that this feature is not directly supported, I will try to come up with creative solutions to achieve my goal. Maybe I will change the tags for an "excluded" card from "A", "B", and "C" to "not-A", "not-B", and "not-C".

The response from matthewD is more complicated than I want to take on right now. I can program, though I don't know Python. I want to keep the solution very simple and low tech as I can easily become distracted on programming issues. Nevertheless I thank you matthewD.
