AWS Elasticsearch：搜索时出现“ too_many_clauses”异常

问题描述

我对Elasticsearch功能非常陌生。我使用AWS Elasticsearch + Kibana。对于某些查询，我会收到一个例外：

ElasticsearchClientException: Request Failed to execute. 
Call: Status code 500 from: POST /my-data/_search?pretty=true&error_trace=true&typed_keys=true. 
ServerError: Type: search_phase_execution_exception Reason: "all shards Failed" 
CausedBy: "Type: too_many_clauses Reason: "maxClauseCount is set to 1024"

我已经使用一种将maxClauseCount设置为更大的数量的解决方案复习了该主题，但是该选项在AWS ES中不可用。有人可以帮助我更新AWS ES设置以解决此问题或查看我的nesT请求（我读过一个选项，认为错误的请求是导致此异常的原因）。

这是我的nesT请求：
