How to filter out all notes that link to certain file

Hi ~ Excuse me, a small question, what type of value is expected for the Incoming/Outgoing item links filter condition in smart group? Is it a number? If I want to filter out all notes that link to certain file, how should I set it?

That is looking for the number of outgoing links.
There is no criteria specifically for filtering based on the content of item links.

Thanks! Looking forward to a similar feature in DT someday~

You can view the items linking to a file (via item links or Wiki links) via the Document > Links inspector.
