It can quickly store, search, and analyze massive amounts of data. It is used by Wikipedia, Stack Overflow, and Github.The bottom of the Elastic is the Open Source Library Lucene. However, you cannot use Lucene directly, you must write your own code to invoke its interface. The Elastic is a Lucene package that provides the operating interface of the REST API and is available out of the box.This article starts from scratch and explains how to use Elastic to build your own full-text search engine.
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
