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.
