I am switching from lucene which was primary fulltext provider for my project and i cant find sollution for my issue: I need to be able to recreate all (or some part of) elasticsearch data in background while previous revision still will be online. In lucene which was filebacked i was solving this by symlinks and it was very effective. Does anybody knows some formula how to do this in elasticsearch? Thank you. ---
