Using a suitable query, find() can be used as a special item or group designator. The function returns a List of the $Path value for every matching note. The likely order of the returned items is $OutlineOrder ascending but it cannot be assumed. If sort order matters apply and explicit sort operation before further use.
In an item-scope context, care should be taken in constructing the query so that only one note is matched.
