Also, in sdk 1.2.2: Datastore indexes on single properties can now be disabled by setting indexed=False on the property constructor. http://googleappengine.blogspot.com/2009/05/python-sdk-version-122-released.html On Mar 23, 3:08 am, an0 an0...@gmail.com wrote: If so, can I explicitly mark a ListProperty not to be indexed?
