Elasticsearch is a distributed, extensible, real-time search and data analysis engine
Elasticsearch not only full-text search, but also supports structured search, data analysis, complex language processing, geographic location, and inter-object correlation. At the same time, Elasticsearch has super-strong horizontal scalability, which can distribute load pressu
Elasticsearch service.Index on the Elasticsearch server, the first step is to create a connection to the server.Client client = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
2. Create a querybuilder.QueryBuilder you can set a query for a single field, or you can set up multiple fields.e.g.1: Query hibernate The
I briefly introduced Elasticsearch in play with elasticsearch. In this article, we still do some basic learning about how to perform CRUD in Elasticsearch? Suppose we are creating an application similar to Weibo. Let's call it kiwi first. Kiwi is composed of messages. In kiwi, a message is called a ksay

Elasticsearch IntroductionElasticsearch (ES), an open source search engine based on Apache Lucene (TM), can be considered as the most advanced, best-performing and most functional search engine library in the world, whether in open source or proprietary domain.However, Lucene is just a library. To play a powerful role, you need to integrate it into your app using C #. Lucene is very complex, and you need to understand the search knowledge to understan

Elasticsearch is an open-source, distributed, and restful search engine built based on Lucene. Designed for cloud computing, it can achieve real-time search, stable, reliable, fast, and easy to install and use. JSON data indexing is supported through HTTP.We create a website or application and add a search function, which makes it difficult to search. We hope that our search solution will be faster. We h

Elasticsearch provides developers with a set of restful interfaces based on the HTTP protocol, and only needs to construct a rest request and parse the JSON returned by the request for access to the Elasticsearch server.

Working Mechanism of ElasticSearch
Like Solr, ElasticSearch is an enterprise-level search engine that is based on Apache Lucene and has high reliability.
Some concepts in ElasticSearch correspond to relational databases. For example, a database is called an index in ES and a table is called a Type in ES.
The specific relationship is shown in the table below.

The system is Windows Server 2003.Elasticsearch is a stable, distributed, restful search engine based on Lucene. In fact, the so-called restful is that it provides a URL for you to call (indexing and retrieval), but it is too brutal to use it directly. Therefore, it also provides a series of client packages, which are equivalent to encapsulating the curl request, the languages supported by the client package include Java, PHP, Python, Ruby and Perl, a
