<property name="addedDate"  direction="desc" />
</datastore-index>

Result is not coming as expected.order by the addedDate.It results random data not ordered by addedDate Please Help?

Answer 1

Remove the index definition for "Messages". You don't need to define an index on a single property.

Try without an index definition for Messages. You should get the correct results.
