Introduction

Apache Solr is a powerful, open-source search platform used for indexing and querying large amounts of data. When integrated with Spring Boot, it enables you to build robust search functionality within your application. This guide covers how to implement Solr indexing in a Spring Boot application, from configuration to practical examples.

Steps to Implement Solr Indexing in Spring Boot

1. Setting Up Solr in Your Environment

Before integrating Solr with Spring Boot, ensure you have Apache Solr installed and running.

• Download and Install Solr: Download Solr from Apache Solr Downloads and follow the installation guide.

• Start Solr: Use the following command:

• Create a Core: Create a core for your application. For example:

2. Adding Dependencies

Include the necessary Maven dependencies in your pom.xml to enable Solr in Spring Boot.

3. Configuring Solr in Spring Boot

In the application.properties file, add Solr's URL configuration.

4. Creating an Entity and Repository

Define the entity to be indexed and create a repository for Solr operations.
