Thank you for your reply, but I think you have misinterpreted the problem.
PRODUCT TAG has but only 1 option “equal to” it should not. it should have the option CONTAINS
To reproduce the problem try to set up any collection that uses “contains, starts with, ends with” you will see that this critical feature was not engineered into the system…
Simply put YOU CAN NOT EVEN SELECT “contains” AS AN OPTION for TAGS
Try it. lol. you’ll see.
Try to “do” what you have suggested here.
THESE, are not “even available to select” they are DISABLED when TAG is selected in drop menu 1
