# Solr search engine

[Solr search engine](https://github.com/ibexa/solr) allows you to use advanced search features: filtering, query, full-text search, and aggregations.

When you enable Solr and re-index your content, all your existing Search queries by using `SearchService` are powered by Solr automatically. This allows you to scale up your Ibexa DXP installation and be able to continue development locally against SQL engine, and have a test infrastructure, Staging, and Prod powered by Solr. By this, it also removes considerable load from your database.

For more information on the architecture of Ibexa DXP, see [Architecture](https://doc.ibexa.co/en/latest/administration/project_organization/architecture/index.md).
