Hi all,

I seem to remember that there was a way to add custom metadata to an index.  
It's custom because it's not processed nor understood by elastic search nor  
lucene, just stored in the cluster. Do I remember that correctly? Can  
somebody please point me to some info on that topic?

Regards,

Christian

Hi christian,

it's possible to save additional meta fields per mapping:

Additional metadata for an index is not possible as far as I know.  
I had the same issue and helped me out by introducing a "Meta" type.  
I use one "Meta" type document per Index to store index meta data only  
relevant for the application.

Hope I could help

Greetings

What about creating a document type called meta (index : no, store : yes) and put your data here ?
