Elasticsearch requires a minimum of 7 versions of Java, and the Oracle JDK 1.8.0_73 version is recommended when writing this article. Java installation and platform-related, so this article does not intend to describe how to install Java on each platform. Before you install Elasticsearch, run the following command to check your Java version:

Elasticsearch is a distributed RESTful style search and data analysis engine. The biggest difference between the elasticsearch of personal understanding and the traditional relational database is that it can be structured search, full-text retrieval and data analysis. This article briefly describes how to complete the Elasticsearch RESTful API functionality with
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 packag
By adding search data through the rest API, reading the official documentation reveals that Elasticsearch supports dynamic mapping, but there are a lot of questions and listen slowly.

The fourth method is to use a plug-in-river. River runs on ElasticSearch and can import data from an external database to ES. It should be noted that data construction is only performed on shards, but not on copies.
