Hi Johnny,

How quickly are you starting and quitting ElasticSearch? There shouldn't be
anything special needed to get ES to serialise to disk, but given it
flushes to the index asynchronously I suspect you might be able to cause
loss of data if you kill it fast enough and sufficiently aggressively
(SIGKILL or similar).

If you're still seeing this, it sounds like ES is misconfigured -- perhaps
it doesn't have appropriate permissions on its data directory?

Thanks Nick, that is fair enough.

Actually I tried annotator-store first, and got it up and running. I
noticed that I lost all my annotations after I shut down the store and
ElasticSearch. Is there a way to get the store permanent?

Kind regards,
