Hi. I'm very to elasticsearch, so please excuse my lack of knowledge. I normally insert stuff inside indices using the java api, and read them by parsing the JSON aquired by querying to `http://localhost:9200/portail/_search?pretty=true&sort=date` for example. I've realised the sort option wasn't working, probably due to my date format. I heard you could edit the format / add a new one in the mappings. How do I edit that ? I know you can view them by querying \_mappings via URL, but how can I edit them ? Is that in the config file or something ? Thanks

Hi.

How about this page?  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html#\_example\_mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html#_example_mapping)

I think It's useful to you.

And cannot change mapping stocked data already. (It's possible make new field via scheme-less)  
It's better make another index with new mappings I think.

Good luck!
