elasticsearch客户端执行查询 lucene中 searchService.executeQueryPhase 执行耗时:16ms 为啥整个调用时间得157ms 耗时主要在哪里啊?

追根溯源:The took time in the response contains the milliseconds that this request took for processing, beginning quickly after the node received the query, up until all search related work is done and before the above JSON is returned to the client. This means it includes the time spent waiting in thread pools, executing a distributed search across the whole cluster and gathering all the results.

took只是query的时间,不包括fetch的时间。且不包括网络延时
