我在使用Elasticsearch进行search查询的过程中，出现了Result window is too large问题。
这里简单做一个报错复现：

从上面的报错信息，可以看到ES提示我结果窗口太大了，目前最大值为10000，而我却要求给我10000000。并且在后面也提到了要求我修改index.max_result_window参数来增大结果窗口大小。
我google了修改方法，命令如下：
|
1
|
curl -XPUT http:
//127
.0.0.1:9200
/cmdb-now/_settings
-d
'{ "index" : { "max_result_window" : 100000000}}'
|
需要注意的是，cmdb-now这里是我ES索引的名字，因此你需要它替换成你对应的索引名称进行修改。
