Nested issue for Java api (in urgency)!


(koqiui) #1

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 ---------------------
[
//100
{
"name": "王思聪",
"age": 42,
"desc": "国民老公",
"keywords": ["国民", "国民老公"],
"friends": [{
"name": "王娜",
"age": 29,
"gender": "女"
}, {
"name": "老李",
"age": 50,
"gender": "男"
},
{
"name": "小花",
"age": 25,
"gender": "女"
}
]
},
//200
{
"name": "东东",
"age": 27,
"desc": "小可爱",
"birthdate": "1992-12-25",
"keywords": ["国民", "国民老婆"],
"friends": [{
"name": "大花",
"age": 46,
"gender": "女"
},
{
"name": "小王",
"age": 32,
"gender": "男"
}
]
},
//300
{
"name": "老杨",
"age": 55,
"birthdate": "2000-01-13",
"keywords": ["老男神"],
"friends": [{
"name": "小花",
"age": 25,
"gender": "女"
}]
},
//400
{
"name": "小豹王",
"age": 35,
"desc": "野蛮小将军",
"keywords": ["男神"],
"friends": [{
"name": "李斌",
"age": 32,
"gender": "男"
},
{
"name": "王娜",
"age": 29,
"gender": "女"
},
{
"name": "超杰",
"age": 36,
"gender": "男"
}
]
},
//500
{
"name": "光明",
"age": 23,
"desc": "我们的宝贝儿",
"keywords": ["男神", "帅哥"],
"friends": [{
"name": "小冰",
"age": 36,
"gender": "女"
},
{
"name": "超杰",
"age": 36,
"gender": "男"
}
]
}
]


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:

```
CODE
```

About "urgency" in the title, it's useless.

Read this and specifically the "Also be patient" part.
