        Arguments:
            material_ids (str, List[str]): A single Material ID string or list of strings
                (e.g., mp-149, [mp-149, mp-13]).
            e_total (Tuple[float,float]): Minimum and maximum total dielectric constant to consider.
            e_ionic (Tuple[float,float]): Minimum and maximum ionic dielectric constant to consider.
            e_electronic (Tuple[float,float]): Minimum and maximum electronic dielectric constant to consider.
            n (Tuple[float,float]): Minimum and maximum refractive index to consider.
            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.
                Default is material_id and last_updated if all_fields is False.

        Returns:
            ([DielectricDoc], [dict]) List of dielectric documents or dictionaries.
