Offline Elasticsearch Exporter

Hi!
Is there any way to perform data export from Elasticsearch data path without starting the Elasticsearch?
Some googling tells me there are some tools out there to perform this, but all of them require Elasticsearch to be up.
i.e. I need something that can read the lucene indexes directly and export the documents into csv/json/any other format.

Thank you!

There's nothing that we support, no.

I have heard incidental reports (from a while ago now) of http://www.getopt.org/luke/ working when people have wanted to recover bad shards, you could try that, but see my first comment.
