Hi All, We are using elastic-search for our project. We would like to implement a feature in our project using elastic search. We want to make sure that all the saved documents in our project must contain certain field(s) e.g. { USER\_ID:"123" USER\_NAME:"Ashutosh" } In other words, if the document does not contain the mandatory fields e.g. USER\_ID, it will not be saved. It will be helpful, if you share your ideas whether it is possible to define mandatory filed(s) of a document in elastic search? Thanks for your help. Best, Ashutosh -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Clinton, Thank you for your quick response. Presently, we are handling it in our application but it would have been better for us if we could have difined some kind of mappiing for the elasticsearch index to make the fielad(s) mandatory.

The best you can do is reject any documents with fields not explicitly declared in your mapping. Like Clinton said, mandatory fields are best handled at the client side. -- Ivan On Wed, May 15, 2013 at 6:32 AM, Ashutosh Bhattacharya \< [ashutosh.bhattacharya.in@gmail.com](mailto:ashutosh.bhattacharya.in@gmail.com)\> wrote: > Hi Clinton, > > Thank you for your quick response.
