刪除通過查詢不工作

Question

我想刪除文件的日期比12月1日低，但它看起來不像它實際上刪除任何東西。

我試着使用刪除通過查詢API：

curl -XPOST "http://localhost:9200/mediadata/events/_delete_by_query" -d' 
{ 
    "query": { 
    "range": { 
     "created_at": { 
     "lt": "2016-12-01 00:00:00" 
     } 
    } 
    } 
}' 

或者這句法：

curl -XDELETE 'http://localhost:9200/mediadata/events/_query' -d ... 

我得到這種結果：

{"_index":"mediadata","_type":"events","_id":"_delete_by_query","_version":10,"_shards":{"total":3,"successful":2,"failed":0},"created":false} 

在此先感謝。

編輯：這裏是映射：

Answer 1

你的語法確實是正確的。在版本5.x中，通過查詢刪除如下。

POST mediadata/events/_delete_by_query?conflicts=proceed 
{ 
    "query": { 
    "range": { 
     "created_at": { 
     "gt": "2016-11-02 00:00:00" 
     } 
    } 
    } 
} 

現在的基礎上，你是從ES

{"_index":"mediadata","_type":"events","_id":"_delete_by_query","_version":10,"_shards":{"total":3,"successful":2,"failed":0},"created":false} 

得到我會假設你正在運行2.x版，其中的語法是不同的反應。

首先，在版本2.x通過查詢刪除是，你需要使用安裝插件：

plugin install delete-by-query 

然後運行它：

curl -XDELETE "http://localhost:9200/mediadata/events/_query" -d' 
{ 
    "query": { 
    "range": { 
     "created_at": { 
     "gt": "2016-11-02 00:00:00" 
     } 
    } 
    } 
}' 

響應看起來像：

{ 
    "took": 0, 
    "timed_out": false, 
    "_indices": { 
    "_all": { 
     "found": 1, 
     "deleted": 1, 
     "missing": 0, 
     "failed": 0 
    }, 
    "mediadata": { 
     "found": 1, 
     "deleted": 1, 
     "missing": 0, 
     "failed": 0 
    } 
    }, 
    "failures": [] 
} 

完整的示例：

PUT mediadata 
{ 
    "mappings": { 
      "events": { 
       "properties": { 
        "channels": { 
         "properties": { 
          "kdata": { 
           "type": "string",
