       "filter": {
           "gt": 10,
           "lt": 50
       }
   }
}

Note that the value of the metadata field hasAgeAtDiagnosis is a dictionary containing the key filter, whose value is a further dictionary with keys gt (greater than) and lt (less than) for the upper and lower bounds to filter by.

You can use either integers or strings (like "10") as the upper and lower bounds in filter, in the query above.
