Parameters
----------
query : str
A string of the query, e.g. "af-id(60021784)".

Whether to refresh the cached file if it exists or not. If int
is passed, cached file will be refreshed if the number of days

The number of entries to be displayed at once. A smaller number
means more queries with each query having less results.
download : bool (optional, default=True)
Whether to download results (if they have not been cached).
integrity_fields : None or iterable (default=None)
Iterable of field names whose completeness should be checked.
ScopusSearch will perform the action specified in

helps avoiding idiosynchratically missing elements that should
always be present, such as the EID or the name.
integrity_action : str (optional, default="raise")
What to do in case integrity of provided fields cannot be
verified. Possible actions:
- "raise": Raise an AttributeError
