Hi, You need to retrieve all objects that were written in this period out of the datastore and re-put them - single-property indexes are only written on putting the entity. If you can't work out which entities were written in this period, then you will need to retrieve all entities and re-put them.
It should be noted that query indexes, which use these single-property indexes in the background, are re-generated on deployment.
