elasticsearch提示 Data too large

jvm堆内存不够当前查询加载数据所以会报data too large, 请求被熔断，indices.breaker.request.limit默认为jvm heap的60%, 看一下集群里这个参数的设置。文档见：https://www.elastic.co/guide/e ... .html
下面的那个curl操作添加下header:  curl -XPOST -H "Content-Type:application/json"

谢谢回答。
我用curl  -H "Content-Type:application/json" -XPOST 'http://localhost:9200/elasticsearch/_cache/clear' -d '{ "fielddata": "true" }'  命令的结果：

{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"elasticsearch","index_uuid":"_na_","index":"elasticsearch"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"elasticsearch","index_uuid":"_na_","index":"elasticsearch"},"status":404}

简单的把indices.breaker.request.limit的值 设置为jvm heap的100%或者200%，有效吗？
还有，这个值在哪里设置，是/etc/elasticsearch/jvm.options里？

非常感谢，我运行清理fileddata cache的命令，结果是：

{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"elasticsearch","index_uuid":"_na_","index":"elasticsearch"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"elasticsearch","index_uuid":"_na_","index":"elasticsearch"},"status":404}

找不到 index是什么原因？

使用以上命令清空缓存以后，kibana仍然提示出错，kibana的日志：
kibana[4844]: FATAL  [circuit_breaking_exception] [parent] Data too large, data for [<http_request...=145446

问题还是存在 。
