What is the right KQL syntax to query for all documents where a given managed metadata property, "Document Category" has the value of a term which exists under a given parent term, "Sales and Marketing" in the term hierarchy?
Document Category (Term set) | |--- Sales and Marketing | | | |--- Some Document Category 1 | | | |--- Some Document Category 2 | |---- Some other category | | . . .
What we want is all documents where the property "Document Category" on the document has a value that is one of the terms under the "Sales and Marketing" node.
