ES更改參數max_result_window

今天開發那邊說翻頁超過10000報錯。早上來查閱官網手冊，說from/size默認是10000。通過參數index.max_result_window進行控制。那么直接改這個參數即可。

1、先看看默認配置

curl -XGET 10.46.2.100:9200/carnoc_jobapply/_settings

 

{
  "carnoc_jobapply": {
    "settings": {
      "index": {
        "number_of_shards": "1",
        "provided_name": "carnoc_jobapply",
        "creation_date": "1554089572018",
        "analysis": {
          "ik": {
            "tokenizer": "ik_max_word"
          }
        },
        "number_of_replicas": "1",
        "uuid": "ccF77NAHTfiec5-ugvZPfA",
        "version": {
          "created": "6010299"
        }
      }
    }
  }
}

沒有具體的值，采用的是默認的參數值10000。

2、進行更改參數

curl -XPUT 10.46.2.100:9200/carnoc_jobapply/_settings -d '{ "index.max_result_window" :"500000"}'

拋了個異常

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

這是由於從ES6.0開始需要指定header頭，重新編輯下

curl -H "Content-Type: application/json" -XPUT 10.46.2.100:9200/carnoc_jobapply/_settings -d '{ "index.max_result_window" :"500000"}'

返回結果

{"acknowledged":true}

3、再次查看參數值

curl -XGET 10.46.2.100:9200/carnoc_jobapply/_settings

返回

{
  "carnoc_jobapply": {
    "settings": {
      "index": {
        "number_of_shards": "1",
        "provided_name": "carnoc_jobapply",
        "max_result_window": "500000",
        "creation_date": "1554089572018",
        "analysis": {
          "ik": {
            "tokenizer": "ik_max_word"
          }
        },
        "number_of_replicas": "1",
        "uuid": "ccF77NAHTfiec5-ugvZPfA",
        "version": {
          "created": "6010299"
        }
      }
    }
  }
}

修改成功

注意：

1、此方法是設置單索引，如果需要更改索引需要將carnoc_jobapply換成_all

2、即使換成_all，對於新增的索引，還是默認的10000
