-        Get integer location slice for requested label or tuple
+        Get both the location for the requested label(s) and the
+        resulting sliced index.
 
         Parameters
         ----------
-        key : label or tuple
-        level : int/level name or list thereof
+        key : label or sequence of labels
+        level : int/level name or list thereof, optional
+        drop_level : bool, default True
+            if ``False``, the resulting index will not drop any level.
 
         Returns
         -------
-        loc : int or slice object
+        loc : A 2-tuple where the elements are:
+              Element 0: int, slice object or boolean array
+              Element 1: The resulting sliced multiindex/index. If the key
+              contains all levels, this will be ``None``.
