                 (e.g. ['A-B(6)', 'A-B(3)']).
            max_bond_length (Tuple[float,float]): Minimum and maximum value for the maximum bond length
                in the structure to consider.
            mean_bond_length (Tuple[float,float]):  Minimum and maximum value for the mean bond length

                in the structure to consider.
            sort_fields (List[str]): Fields used to sort results. Prefixing with '-' will sort in descending order.
            num_chunks (int): Maximum number of chunks of data to yield. None will yield all possible.
            chunk_size (int): Number of data entries per chunk.
            all_fields (bool): Whether to return all fields in the document. Defaults to True.
            fields (List[str]): List of fields in DielectricDoc to return data for.
