            Parameters:
                ekey (str or int): Path in Plex to fetch items from. If an int is passed
                    in, the key will be translated to /library/metadata/<key>. This allows
                    fetching an item only knowing its key-id.

                    with the best guess PlexObjects based on tag and type attrs.
                etag (str): Only fetch items with the specified tag.
                **kwargs (dict): Optionally add attribute filters on the items to fetch. For
                    example, passing in viewCount=0 will only return matching items. Filtering
                    is done before the Python objects are built to help keep things speedy.
                    Note: Because some attribute names are already used as arguments to this
                    function, such as 'tag', you may still reference the attr tag byappending
                    an underscore. For example, passing in _tag='foobar' will return all items
                    where tag='foobar'. Also Note: Case very much matters when specifying kwargs
                    -- Optionally, operators can be specified by append it
                    to the end of the attribute name for more complex lookups. For example,
                    passing in viewCount__gte=0 will return all items where viewCount >= 0.
                    Available operations include:

                    * __contains: Value contains specified arg.
