使用sql插件执行如下语句的时候报错
http://10.127.0.1:9200/\_sql?sql=select * from test limit 1000000

错误信息：
{"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 [1000000].

意思是返回结果太大，目前最大值是10000，而我却要求返回1000000条数据。可以设置索引的index.max_result_window属性返回结果的大小

put http://10.127.0.1:9200/test/_settings
{
"index.max_result_window":1000001
}
