Review Comment:
I am not sure what the semantics of this would be. I think we should not
violate the semantics of the `addDocuments` API that guarantees the insert
order being preserved across merges etc. from that perspective I think it's
actually good that we don't do that?
Also if you rely on a certain order you should sort it ahead of time or at
retrieval time.
