This shows a failing test that I'm unable to figure out what I'm doing wrong.

Account string
}

collectionName := "Foo"
accountName := "[email protected]"
ctx, err := aetest.NewContext(nil)
if err != nil {
t.Fatalf("Failed to create context: %v", err)
}
defer ctx.Close()
item := Foo{Account: "[email protected]"}
ancestorKey := datastore.NewKey(ctx, "Account", accountName, 0, nil)

As soon as I posted this gist, I realized the errors of my ways.

Date is not indexed (in fact, I took it out to repro this case) and Order(...) will fail on any unindexed value.
