Item tag 
An item tag is a group of items. They are used when a recipe allows multiple different items as inputs and control many other gameplay features. See below for the use of each item tag. They can also be used when testing for item arguments in commands with #<resource location>, which succeeds if the item matches any of the items specified in the tag, and can be searched in the creative inventory by searching #<resource location>.
