            A dictionary with two possible objects, ''lower'' and ''upper''. At least one must be present and a non-null value.


            The expected data type for these values is defined by the `range` filter''s `data_type` (see response linked above).


            If the data_type is a date, string format should be a parseable ISO8601 date string. Date values should be provided as a string in ISO 8601 format.


            Leaving a value as null will result in that bound being set to the lowest or highest possible value, depending on whether it is the upper or lower bound.'
