I looked at the JIRA ElasticSearch for a Bump Button on Jira and found none.
I guess the best answer to both responses is how to use DCP ptorocol along with some sort of triggering mechanism to grab the document and send it onward to the deep archive (or elastic search or Hadoop), while at the same time being able to search the bucket for any buckets yet to be sent and send them.
I could even see XDCR have an option to not pass along document deletes along with the “Pause” option currently availble.
