Have you read the File Metadata Search Programming Guide? You can find it here <https://developer.apple.com/library/content/documentation/Carbon/Conceptual/SpotlightQuery/Concepts/QueryFormat.html#//apple_ref/doc/uid/TP40001849-CJBEJBHH> According to that document, only a very limited subset of predicate syntax is supported, and it uses special parsing rules.
