(not query Word query) may be parsed as a query word Foo,bar, which matches the query term saved in the index. This is the parsing process (which includes indexing and searching), which allows ES to make full-text queries.Cluster clusterOne or more nodes that have the same cluster name make up a cluster. Each cluster automatically selects a master node, and if the primary node fails, the cluster automatically selects the new primary node to replace the failed node.Document documentsA document i
