How can I mask Data in Elastisearch Index field.

Ex: Have a Description field which contains email id inside it

I just want to replace the email id with some string 'xxx' and leave other part of description as it.

Is there any filter available to do this

Thanks & Regards,  
Avijit

You probably need to do that in your application layer. You can totally hide fields from the user depending on the roles this user has. This requires a platinum commercial license though.

You can at index time replace the value by a fingerprint though. That could May be solve your use case.

use Spring Elastic Data and add listener to encrypt and decrypt before and after Data load and data pull respectively.
