ES version : 2.4.4
We need Nested Query in our business , so I write code as ES doc says, but failed.
My Doc Mapping coded as the following :
------------------------ doc mapping --------------------------
{
"properties": {
"name": {
"type": "string",
"analyzer": "ik"
},
"age": {
"type": "integer"

}

I can index ( as well as query ) the doc data with other rest api client， but when I index the data with java api client, it goes wrong, the error message is : cant be changed from nested to Non nested 。
I have tried "dynamic : false/strict” to avoid changing field types, but still not work.
Anyone can figure it out ?
Many thanks !!!
