It would be most functional to be able to stack with the OR function when it is set to 'contains' because it makes it easier to forget to go back and change it when you built it in 'equals'.

Plus, if you want to make edits and add more tags you have to go change it back to 'equals', make the additions, and change it back to 'contains'.

This update would make for a smoother and more streamlined function.
