How to know that which particular Document is successfully Pull from Couchbase server?


I am trying to do push and pull Replications. I have created a document and it is getting successfully pushed to server DB. I get the successful Sync count in the Push and Pull Replication change using Observer but not exactly get the Pulled Synced Document IDs that are synced.
So My question is how to get the document Id of the successfully Pulled synced Document or is there any property for the document which says that the document is successfully synced (Pull syncing)?
