Hi,
thanks for the reply.
There isn't other way to do that?
Using REST you can send json like this :
curl -XPOST 'localhost:9200/customer/external?pretty&pretty' -H
'Content-Type: application/json' -d'
{
"name": "Jane Doe"
}
'
In my case I have json like this:
{
"filters" : {
"id" : 1,
"name": "abc"
}
}
how can I treat this cases? There isn't a way to send all the json element
and index it like the in the REST request?
Thanks.
