Result window is too large, from + size must be less than or equal to: [10000]

1、使用elasticsearch做分頁查詢時，當查詢記錄超過10000時，會報如下錯誤：

Result window is too large, from + size must be less than or equal to: [10000]

elasticsearch默認只能查詢到10000

index.max_result_window
The maximum value of from + size for searches to this index.
 Defaults to 10000. Search requests take heap memory and time proportional to from + size and this limits that memory.
See Scroll or Search After for a more efficient alternative to raising this.

解決方法：

PUT policy_document/_settings
{
  "index":{
    "max_result_window":1000000
  }
}
