elasticsearch 查询结果最大默认10000

elasticsearch 查询结果默认最大是 10000
可以通过 index.max_result_window 参数进行修改
https://www.elastic.co/guide/en/elasticsearch/reference/6.7/index-modules.html

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.

官方文档的建议是不要修改，太大会影响性能和效率，建议使用 scroll 来代替。
如果十分想要修改可以：
