Hi,

I am new to No SQL, so a very basic questions from my side..  
Does all fields in a document are indexed in elastic?

- If Yes, Does the data size increases over time?
- If not what is the performance of query on a non-indexed fields?

Thanks!  
Kiran

Yes.

Not sure I understood. If you don't index new data, no the size will remain the same.

You can't query non indexed fields.
