Elasticsearch：路径下的嵌套对象不是嵌套类型 [英] Elasticsearch: nested object under path is not of nested type

问题描述

我一直在尝试搜索包含嵌套字段的文档。我创建了这样的嵌套映射：

  {
message：{
properties {
message：{
type：nested，
properties：{
message_id：{type：string}，
message_text：{type：string}，
message_nick：{type：string} 
} 
} 
} 
} 
} 
  

我的搜索如下所示：

  curl -XGET'localhost：9200 / thread_and_messages / thread / _search'\ 
 -d'{query：{bool ：{必须：{匹配：{thread_name：香蕉}}，{嵌套：{路径：消息，查询：{bool ：[{match：{messages.message_text：Banana}}]}}}}}}}}'
  

但是我收到此错误消息：

  QueryParsingException [[thread_and_messages] [嵌套]嵌套对象under path [messages]不是嵌套类型] 
  

编辑

我仍然收到此错误。我通过Java这样做，所以这是我要创建的文档：

  {
_id： {
path：3，
thread_id：3，
thread_name：Banana，
created：Wed Mar 25 2015 ，
first_nick：AdminTech，
messages：[
 {
message_id：9，
message_text：香蕉，
message_nick：AdminTech
} 
] 
} 
} 
  

如下创建索引：

  CreateIndexRequestBuilder indexRequest = client.admin（） .indices（）。prepareCreate（INDEX）.addMapping（message，mapping）; 
  

我认为我可能会错误地索引文档。

解决方案

TLDR：在您的嵌套类型中放入type：nested，

$ b $说我们有一个普通的类型，另一个类型嵌套在它中：

  {
some_index：{
mappings：{
normal_type：{
properties：{
nested_type：{
type nested，
properties：{
address：{
type：string
}，
country：{
type：string
} 
} 
}，
first_name：{
type：string
} ，
last_name：{
type：string
 } 
} 
} 
} 
} 
} 
  

嵌套查询工作所需的类型：嵌套行是path：分配给 nested_type ，如下所示：

  GET / some_index / normal_type / _search 
 {
查询：{
嵌套：{
查询：{
bool：{} 
}，
path：nested_type
} 
} 
} 
  

仅在较新的Elasticsearch版本（自1.1.1？起）以来，type：nested， / p>


I've been trying to search on my document which contains a nested field. I created the nested mapping like this:

{
  "message": {
    "properties": {
      "messages": {
        "type": "nested",
        "properties": {
          "message_id": { "type": "string" },
          "message_text": { "type": "string" },
          "message_nick": { "type": "string" }
        }
      }
    }
  }
}

My search looks like this:

curl -XGET 'localhost:9200/thread_and_messages/thread/_search' \
     -d '{"query": {"bool": {"must": [{"match": {"thread_name": "Banana"}}, {"nested": {"path": "messages", "query": {"bool": {"must": [{"match": {"messages.message_text": "Banana"}}]}}}]}}}}'

Yet I am receiving this error message:

QueryParsingException[[thread_and_messages] [nested] nested object under path [messages] is not of nested type]

EDIT

I am still receiving this error. I am doing this via Java so this is the document I am trying to create:

{
  "_id": {
    "path": "3",
    "thread_id": "3",
    "thread_name": "Banana",
    "created": "Wed Mar 25 2015",
    "first_nick": "AdminTech",
    "messages": [
      {
        "message_id": "9",
        "message_text": "Banana",
        "message_nick": "AdminTech"
      }
    ]
  }
}

Creating the index like so:

CreateIndexRequestBuilder indexRequest = client.admin().indices().prepareCreate(INDEX).addMapping("message", mapping);

I think I am possibly indexing the document incorrectly.

解决方案

TLDR: Put "type": "nested", in your nested type.

Say we have a normal type, and another type nested in it:

{
   "some_index": {
      "mappings": {
         "normal_type": {
            "properties": {
               "nested_type": {
                  "type": "nested",
                  "properties": {
                     "address": {
                        "type": "string"
                     },
                     "country": {
                        "type": "string"
                     }
                  }
               },
               "first_name": {
                  "type": "string"
               },
               "last_name": {
                  "type": "string"
               }
            }
         }
      }
   }
}

The "type": "nested", line is required for the nested queries to work which have "path": assigned to nested_type, like this:

GET /some_index/normal_type/_search
{
  "query": {
    "nested": {
      "query": {
        "bool": {}
      },
      "path": "nested_type"
    }
  }
}

The "type": "nested", line seems to be required in newer Elasticsearch versions only (since 1.1.1 ?).
