"""Query phonon docs using a variety of search criteria.
Arguments:
material_ids (str, List[str]): A single Material ID string or list of strings
(e.g., mp-149, [mp-149, mp-13]).
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 PhononBSDOSDoc to return data for.
Default is material_id, last_updated, and formula_pretty if all_fields is False.
Returns:
