Result window is too large, from + size must be less than or equal to: [10000] but was [13314300]

由於前端沒有從Es請求到數據,用postman測試接口是否有問題,結果報錯:Result window is too large, from + size must be less than or equal to: [10000] but was [13314300]。

這是因爲用Elasticsearch做分頁查詢時，Es查詢結果集默認是10000，結果集大小是int，最大爲21億左右（2^32 - 1），將窗口的最大結果集設置爲20億就可以了。

使用head插件設置方法如下圖所示：

索引名稱/_settings?preserve_existing=true,選擇PUT

{"max_result_window":2000000000}

提交請求，出現{"acknowledged": true} ,則說明修改成功。
