+Create Multiple Indexes
+~~~~~~~~~~~~~~~~~~~~~~~
+
+.. include:: /includes/cakeSales-example-collection.rst
+
+The following example creates multiple indexes on the ``cakeSales``
+collection:
+
+.. code-block:: javascript
+
+   db.cakeSales.createIndexes( [
+      { "type": 1 },
+      { "orderDate": 1 },
+      { "state": 1 },
+      { "orderDate": 1, "state": -1 }
+   ] )
+
+The first three indexes are on single fields and in ascending order
+(``1``).
+
+The last index is on ``orderDate`` in ascending order (``1``) and
+``state`` in descending order (``-1``).
