标签：提示 ast mamicode 查询 调整 too group from http
分页查询场景，当查询记录数超过 10000 条时，会报错。
使用 Kibana 的 Dev Tools 工具查询 从第 10001 条到 10010 条数据。
查询语句如下：
GET alarm/_search { "from": 10000, "size": 10 }
查询结果，截图如下：
报错信息如下：
{ "error": { "root_cause": [ { "type": "query_phase_execution_exception", "reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [10010]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting." } ], "type": "search_phase_execution_exception", "reason": "all shards failed", "phase": "query", "grouped": true, "failed_shards": [ { "shard": 0, "index": "alarm", "node": "hdLJanxRTbmF52eK6-FFgg", "reason": { "type": "query_phase_execution_exception", "reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [10010]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting." } } ] }, "status": 500 }
Elasticsearch 默认查询结果最多展示前 10000 条数据。
按照报错信息里的提示，可以看到，通过设置 max_result_window 的值来调整显示数据的大小：
This limit can be set by changing the [index.max_result_window] index level setting.
两种方式可以实现：
修改Elasticsearch 集群中的 配置文件 config/elasticsearch.yml
在配置文件最后增加一行，如下：
max_result_window: 200000000
具体操作命令，如下（比如，设置可查询 200000000 条数据，其中 alarm 是index名称）：
PUT alarm/_settings { "max_result_window" : 200000000 }
命令执行效果，截图如下：
再次执行查询语句，即可正常查询，效果截图如下：
