Suppose you have a key named “user_ids” which all your user ID’s under it, you can use a List Viewer to show the user ID’s like this

What if I only want specific “user IDs”, not all of them? For example with OCR. When the OCR reads some text, and it contains some of the words under the key “milk”, but not all of them, how do I set the list viewer items to specifically those values that the OCR read (that are under the key “milk”)?
