ES更改参数max_result_window

今天开发那边说翻页超过10000报错。早上来查阅官网手册，说from/size默认是10000。通过参数index.max_result_window进行控制。那么直接改这个参数即可。

1、先看看默认配置

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"
        }
      }
    }
  }
}

没有具体的值，采用的是默认的参数值10000。

2、进行更改参数

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

抛了个异常

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

这是由于从ES6.0开始需要指定header头，重新编辑下

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

返回结果

{"acknowledged":true}

3、再次查看参数值

curl -XGET 10.46.2.100:9200/carnoc_jobapply/_settings

{
  "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、此方法是设置单索引，如果需要更改索引需要将carnoc_jobapply换成_all

2、即使换成_all，对于新增的索引，还是默认的10000
