Description:
 def find(self, *args, **kwargs):
 """Find and return the files collection documents that match ``filter``. Returns a cursor that iterates across files matching arbitrary queries on the files collection. Can be combined with other modifiers for additional control. For example:: cursor = bucket.find({"filename": "lisa.txt"}, no_cursor_timeout=True) while (yield cursor.fetch_next):
 grid_out = cursor.next_object() data = yield grid_out.read() This iterates through all versions of "lisa.txt" stored in GridFS. Note that setting no_cursor_timeout to True may be important to prevent the cursor from timing out during long multi-file processing work. As another example, the call:: most_recent_three = fs.find().sort("uploadDate", -1).limit(3) would return a cursor to the three most recently uploaded files in GridFS. Follows a similar interface to :meth:`~motor.MotorCollection.find` in :class:`~motor.MotorCollection`. :Parameters: - `filter`: Search query. - `batch_size` (optional):
 The number of documents to return per batch. - `limit` (optional):
 The maximum number of documents to return. - `no_cursor_timeout` (optional):
 The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to True prevent that. - `skip` (optional):
 The number of documents to skip before returning. - `sort` (optional):
 The order by which to sort results. Defaults to None. - `session` (optional):
 a :class:`~pymongo.client_session.ClientSession`, created with :meth:`~MotorClient.start_session`. If a :class:`~pymongo.client_session.ClientSession` is passed to :meth:`find`, all returned :class:`MotorGridOut` instances are associated with that session. .. versionchanged:: 1.2 Added session parameter.
