Nested issue for Java api (in urgency)!

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”

},

“desc”: {

“type”: “string”,

“analyzer”: “ik”

},

“birthdate”: {

“type”: “date”,

“format”: “yyyy-MM-dd||yyyy-MM-dd HH:mm:ss”

},

“friends”: {

“type”: “nested”,

“properties”: {

“name”: {

“type”: “string”,

“analyzer”: “ik”

},

“age”: {

“type”: “integer”

},

“gender”: {

“type”: “string”,

“index”: “not_analyzed”

}

}

}

}

}
-------------------------- sample data ---------------------

[

“friends”: [{

“name”: “小冰”,

“age”: 36,

“gender”: “女”

},

}

]

}

]


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 !!!

Please format your code using </> icon as explained in this guide. It will make your post more readable.
Or use markdown style like:

```

```

About “urgency” in the title, it’s useless.
Read this and specifically the “Also be patient” part.
