1 修改 max_result_window

1.1 概述

Elasticsearch默认max_result_window的值是10000，既然都用到Elasticsearch，那么我们的数据就会远远超过这个值，这时候，我们在查询时，就会报错，提示我们：

Caused by: ElasticsearchException[Elasticsearch exception [type=illegal_argument_exception, reason=Result window is too large, from + size must be less than or equal to: [10000] but was [1253670]. See the scroll api for a more efficient way to request lar

我们只需要将max_result_window的值改大一些，就就可以了。

1.2 修改方式

PUT http://192.168.3.200:9200/索引/_settings
Content-Type application/json
参数：

  1. {
  2.     "index.max_result_window": 目标数
  3. }

响应：

  1. {
  2.     "acknowledged": true
  3. }

1.3 验证修改结果

GET http://192.168.3.200:9200/索引/_settings
响应：

  1. {
  2.     "spring-boot-elasticsearch-sample-phone": {
