Elasticsearch provides a rich set of Java calling interfaces by constructing a client representation. In general, the client is divided into two types of cluster information in terms of client and data (index) aspects of the client. These two categories can be divided into o

Finally, I found the distributed search framework of elasticsearch. As soon as I read it, I thought it was the same. Basically all the features I want include distributed search, distributed indexing, Zero Configuration, automatic partitioning, automatic indexing load, automatic discovery, and restful APIs. So I started to use it, deployed four machines, and impo

Elasticsearch is an open source distributed real-time search and analysis engine that supports cloud services. It is based on the Apache Lucene search engine's class library and provides full-text search capabilities, multi-lingual support, a dedicated query language, support for geolocation services, context-based

Elasticsearch supports batch addition or deletion of index documents. In Java APIs, bulkrequestbuilder is constructed, batch index/delete requests are added to bulkrequestbuilder, and bulkrequestbuilder is executed. The following is an example: Import static Org. elasticsearch. common. xcontent. xcontentfactory. *; bulkrequestbuilder bulkrequest = client. prepare

Structured Query query interface, which can perform some complex queries on an index. For example, the following example queries the product index, constructs a boolquery, and queries the "pro

In the cluster, the main node is chosen by the main algorithm of ES (the current version 1.2 has a brain fissure problem), and the outside of the cluster can be operated by any node, without the sub-master node (external performance equivalence/de-centering, which facilitates client programming, such as fault re-connection).Index"Index" has two meanings: As a verb, it refers to the process of "saving" a document into
