REST APIs —— Cluster APIs —— Node specification(节点过滤)
https://www.elastic.co/guide/en/elasticsearch/reference/8.8/cluster.html#cluster-nodes
Some cluster-level APIs may operate on a subset of the nodes which can be specified with node filters. For example, the Task Management, Nodes Stats, and Nodes Info APIs can all report results from a filtered set of nodes rather than from all nodes.
一些集群级别的API可能会针对节点的子集进行操作，这可以通过节点过滤器进行指定。例如，Task Management（任务管理）（https://www.elastic.co/guide/en/elasticsearch/reference/8.8/tasks.html）、Nodes Stats（节点统计信息）（https://www.elastic.co/guide/en/elasticsearch/reference/8.8/cluster-nodes-stats.html）和Nodes Info APIs（https://www.elastic.co/guide/en/elasticsearch/reference/8.8/cluster-nodes-info.html）都可以报告来自被筛选节点的结果，而不是所有节点的结果。
