 =========================
 
 .. default-domain:: mongodb
+
+You can delete multiple documents in a collection by using the
+``DeleteMany()`` method. 
+
+The following example specifies a query filter to the ``DeleteMany()``
+method, which matches documents in the ``movies`` collection where the
+``runtime`` field is greater than *800* and deletes all the matching
+documents.
