I found this http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Defining_Indexes_With_Configuration with the following example: <?xml version="1.0" encoding="utf-8"?> <datastore-indexes xmlns="http://appengine.google.com/ns/datastore-indexes/1.0"; autoGenerate="true"> <datastore-index kind="Person" ancestor="false"> <property name="lastName" direction="asc" /> <property name="height" direction="desc" /> </datastore-index> </datastore-indexes>
But I still cannot solve my query error.
