Hello, I'm using elasticsearch as a backend for graylog2. I've seen  
recently that elasticsearch comes with an option that may help me with logs  
since it stores each line as a documment and they are small. The option is  
index.store.compress.stored.

How would I go about configuring this for an already running elasticsearch  
index?  
How would I go about making sure it's actually configured an working?

Thank you.
