Hi Guys,
I want to transformthe creationDate from long to timestamp date ("format" : "MMM/dd/yyyy HH:mm:ss", ). I checked the documentation with no result.
JSON serach result:
"creationDate": 1490254211904,
Mapping of the property:
"creationDate": {
"type": "long"
},
Any idea?
Best regards
Ismael

In elasticsearch?
You can't really change the internal format or the \_source document (unless you are using date ingest processor) but if you create the right mapping and tell elasticsearch that your field is a date that should work

Bonjour,
Merci David.
I'm using an ESB solution, it create the index, when I change the mapping for creationDate the ESB restore the old mapping.
Best regards
Ismael 😉

re David,
No, I just indicate that our ESB generate the index and I can't change the
mapping of the index.

Create an index template in elasticsearch then. It will be applied to the index when it gets created.
