Using Elasticsearch in Spring Boot to implement product search function

Author: Zen and the Art of Computer Programming

1 Introduction

Elasticsearch is an open source distributed search engine that provides a distributed, RESTful search interface. The search solution based on Elasticsearch can easily handle complex retrieval scenarios and provide high scalability. In web applications, Elasticsearch can serve as a background service to support users' retrieval needs. This article will teach you how to use the Spring Boot framework to integrate Elasticsearch to implement product search functions.

This article will use a complete Spring Boot project to show how to use Elasticsearch for product search. The whole process is divided into the following main steps:

1. Install and start the Elasticsearch service;
2. Create Elasticsearch index;
3. Integrate Elasticsearch in Spring Boot project;
4. Add code for search function;
5. Test the search functionality.

2.1 Introduction to Elasticsearch

Elasticsearch is an open source search server built on Apache Lucene. It is a distributed real-time file storage that can accommodate large amounts of data and provide high real-time search capabilities. Elasticsearch provides a RESTful API interface to facilitate developers to communicate with search engines through HTTP requests. Lucene is the core library of Elasticsearch and the most popular full-text search engine in the Java world.

2.2 Elasticsearch index (index)

Data in Elasticsearch is stored in indexes. Whenever you ask E
