+        The result is a stream of data for each CandID that matched by the query. Candidates are separated by an ASCII record separator (0x??). Each cell within the candidate is separated by an ASCII ?? separateor (0x??). Each row should have the exact number of fields that were in the query fields attribute.
+        
+        Within each cell, the format of the data varies based on the dictionary of the field type. If the data is candidate scoped, a value is directly returned. If it is session scoped variable or has cardinality of many:one, a JSON object is returned.
