Elasticsearch：下路[消息]嵌套的對象是嵌套類型

我有很多在Elasticsearch嵌套類型的映射問題

不，我已經跑這來創建我的索引：Elasticsearch：下路[消息]嵌套的對象是嵌套類型

curl -XPOST 'http://localhost:9200/thread_and_messages' -d 
'{"mappings" : { 
    "message": { 
     "properties": { 
      "messages": { 
       "type": "nested", 
       "include_in_parent": true, 
       "properties": { 
        "message_id": {"type": "string"}, 
        "message_text": {"type": "string"}, 
        "message_nick": {"type": "string"} 
       } 
      } 
     } 
    } 
}}'

那麼這如何我已經索引的文檔：

curl -XPUT 'http://localhost:9200/thread_and_messages/thread/1' -d 
'{ 
    "thread_id":"2", 
    "thread_name":"Windows", 
    "created":"Wed Mar 25 2015", 
    "first_nick":"Admin", 
    "messages":[ 
     {"message_id":"5", "message_text":" Pc with a mouse", "message_nick":"Admin"}, 
     {"message_id":"6", "message_text":"Keyboard", "message_nick":"Admin"}, 
     {"message_id":"7", "message_text":"iPhone", "message_nick":"Admin"}, 
     {"message_id":"8", "message_text":"Gym", "message_nick":"Admin"}]" 
}'

這是我的查詢：

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

我收到此錯誤，即使我已經清楚地映射消息爲嵌套類型：

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

這是因爲你定義的映射類型"message"，但隨後索引你的文檔類型"thread"。所以"thread"類型是動態創建的，但不是嵌套的子類型。我跑了作爲張貼你的代碼，然後看着映射：

GET /test_index/_mapping 
... 
{ 
    "test_index": { 
     "mappings": { 
     "message": { 
      "properties": { 
       "messages": { 
        "type": "nested", 
        "include_in_parent": true, 
        "properties": { 
        "message_id": { 
         "type": "string" 
        }, 
        "message_nick": { 
         "type": "string" 
        }, 
        "message_text": { 
         "type": "string" 
        } 
        } 
       } 
      } 
     }, 
     "thread": { 
      "properties": { 
       "created": { 
        "type": "string" 
       }, 
       "first_nick": { 
        "type": "string" 
       }, 
       "messages": { 
        "properties": { 
        "message_id": { 
         "type": "string" 
        }, 
        "message_nick": { 
         "type": "string" 
        }, 
        "message_text": { 
         "type": "string" 
        } 
        } 
       }, 
       "thread_id": { 
        "type": "string" 
       }, 
       "thread_name": { 
        "type": "string" 
       } 
      } 
     } 
     } 
    } 
}

當我在映射改變"message"到"thread"，並開始了，您的查詢工作的罰款。

這裏是我用來測試它的代碼：
