ElasticSearch, referred to as ES, is a lucene-based distributed full-text Search server, and SQL Server full-text index (fulltext index) a bit similar, are based on word segmentation and segmentation of the full-text search engine, with participle, synonym, stem query function , but ES inherently has distributed and real-time properties.One, install the Java SE EnvironmentInstall the Java JDK and configure the Java_home environment variables:1, downlo

the above structure still does not solve such things as: sorting, aggregation, facet, because we may want to read a lot of unnecessary information.So, another data structure solves this problem: Document Values. This structure is essentially a column-like storage, which optimizes the storage structure with the same type of data.To improve efficiency, elasticsearch can read all of the document value under the index into memory, which greatly increases

server in a cluster that, as part of a cluster, stores your data and participates in the indexing and searching capabilities of the cluster. Like a cluster, a node is also identified by a name, by default, the name is random. This name will be assigned to the node when it is started. This name is important for management, because in this management process, you determine which servers in the network correspond to which nodes in the Elasticsearch clus

centralize logging on CentOS 7 using Logstash and Kibana Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location. It is also useful because it allows you to identify issues across multiple servers by associating their logs within a specific time frame. This series of tutorials will teach you how to install Logstash and Kibana on CentOS, and then how to add more filters to construct your log data.
