The logic for selecting the first and last\n        key in the event either key is missing is such that:\n\n        * The start key will be the smallest key in the database that is\n          larger than the given key (same as ``SEEK_GE``).\n        * The end key will be the largest key in the database that is smaller\n          than the given key (same as ``SEEK_LE``).\n\n        If the start key is greater than the end key, then the keys will be\n        returned in descending order. The logic for selecting the first and\n        last key in the event either key is missing is such that:\n\n        * The start key will be the largest key in the database that is\n          smaller than the given key (same as ``SEEK_LE``).\n        * The end key will be the smallest key in the database that is larger\n          than the given key (same as ``SEEK_GE``).\n\n        .. note::\n\n            If one or both keys is ``None`` and you wish to fetch in reverse,\n            you need to specify a third parameter, ``reverse=True``.\n\n        .. note::\n\n            Rather than using :py:meth:`~LSM.fetch_range`, you can use\n            the :py:meth:`~LSM.__setitem__` API and pass in a slice. The\n            examples below will use the slice API.\n\n        Say we have the following data:\n\n        .. code-block:: python\n\n            db.update({\n              'a': 'A',\n              'c': 'C',\n              'd': 'D',\n              'f': 'F',\n            })\n\n        Here are some example calls using ascending order:\n\n        .. code-block:: pycon\n\n            >>> db['a':'d']\n            [('a', 'A""'), ('c', 'C'), ('d', 'D')]\n\n            >>> db['a':'e']\n            [('a', 'A'), ('c', 'C'), ('d', 'D')]\n\n            >>> db['b':'e']\n            [('c', 'C'), ('d', 'D')]\n\n        If one of the boundaries is not specified (``None``), then it will\n        start at the lowest or highest key, respectively.\n\n        .. code-block:: pycon\n\n            >>> db[:'ccc']\n            [('a', 'A'), ('c', 'C')]\n\n            >>> db['ccc':]\n            [('d', 'D'), ('f', 'F')]\n\n            >>> db[:'x']\n            [('a', 'A'), ('c', 'C'), ('d', 'D'), ('f', 'F')]\n\n        If the start key is higher than the highest key, no results are\n        returned.\n\n        .. code-block:: pycon\n\n            >>> db['x':]\n            []\n\n        If the end key is lower than the lowest key, no results are returned.\n\n        .. code-block:: pycon\n\n            >>> db[:'0']\n            []\n\n        .. note::\n\n            If the start key is greater than the end key, lsm-python will\n            assume you want the range in reverse order.\n\n        Examples in descending (reverse) order:\n\n        .. code-block:: pycon\n\n            >>> db['d':'a']\n            [('d', 'D'), ('c', 'C'), ('a', 'A')]\n\n            >>> db['e':'a']\n            [('d', 'D'), ('c', 'C'), ('a', 'A')]\n\n            >>> db['e':'b']\n            [('d', 'D'), ('c', 'C')]\n\n        If one of the boundaries is not specified (``None``), then it will\n        start at the highest and lowest keys, respectively.\n\n        .. code-block:: pycon\n\n            >>> db['ccc'::True]\n            [('c', 'C'), ('a', 'A')]\n\n            >>> db[:'ccc':True]\n            [('f', 'F'), ('d', 'D')]\n\n            >>> db['x'::True]\n            [('f', 'F'), ('d', 'D'), ('c', 'C'), ('a', 'A')]\n\n        If the end key is higher than the highest key, no results are\n        returned.\n\n        .. code-block:: pycon\n\n            >>> db[:'x':True]\n            []\n\n        If the start key is lower tha""n the lowest key, no results are\n        returned.\n\n        .. code-block:: pycon\n\n            >>> db['0'::True]\n            []\n        ");
