You cannot do a query in App Engine without using an index; there are no full table scans. To query on a property, it needs to be indexed, and to allow for ordering in both directions, there need to be both forward and backward indexes. I'm not sure what the index names are; it's an irrelevant implementation detail. I don't believe that even digging in the low- level datastore API allows you access to the indexes by name. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
