Introduction

Solr is a powerful search platform that enables fast and scalable full-text search and analytics. Integrating Solr with a Spring Boot application allows you to leverage its advanced search features. This guide explains how to set up Solr in Spring Boot, perform indexing, execute queries, and manage search operations effectively.

1. Setting Up Solr in Spring Boot

Adding Dependencies

Include the spring-boot-starter-data-solr dependency in your pom.xml:

Configuring Solr

Specify Solr properties in the application.properties or application.yml file:

Ensure that Solr is running locally or remotely and the specified core (products) exists.

2. Creating Solr Entities and Repositories

Defining an Entity

Use the @SolrDocument annotation to map a class to a Solr document.

Creating a Repository

Use SolrCrudRepository to interact with Solr.

3. Indexing and Querying Data in Solr

Indexing Data

Save data to Solr using the repository.

Querying Data

Retrieve data using repository methods or custom queries.

Custom queries can also be implemented using the @Query annotation:

4. Advanced Solr Operations

Paginated Search

Implement paginated search using Pageable:

Deleting Documents

Delete a document by its ID or query.

Using the SolrTemplate

For more control, use SolrTemplate to interact with Solr.

Practical Example

Example: Full-Text Search

Perform full-text search on the name field.

Conclusion

Integrating Solr with Spring Boot enhances your application's search capabilities by leveraging Solr's full-text search and analytics features. Using Spring Data Solr and SolrTemplate, you can index, query, and manage data efficiently. Whether you're building a simple search feature or a complex analytics tool, Solr integration with Spring Boot is a powerful solution.
