(self, indexes)
return names
Create one or more indexes on this collection.

          >>> index1 = IndexModel([("hello", DESCENDING),
          ...                      ("world", ASCENDING)], name="hello_world")

          ["hello_world", "goodbye_-1"]

        :Parameters:
          - `indexes`: A list of :class:`~pymongo.operations.IndexModel`
            instances.

        .. note:: `create_indexes` uses the `createIndexes`_ command
           introduced in MongoDB **2.6** and cannot be used with earlier
           versions.

        .. note:: The :attr:`~pymongo.collection.Collection.write_concern` of
           this collection is automatically applied to this operation when using
           MongoDB >= 3.4.

        .. versionchanged:: 3.4
           Apply this collection's write concern automatically to this operation
           when connected to MongoDB >= 3.4.
        .. versionadded:: 3.0
