About Apache Solr
Apache Solr is an open-source search server built on Apache Lucene. It handles full-text search, vector search and geospatial queries.
What it does
Solr indexes documents and serves fast search and navigation features, such as faceted results and filters. It runs as a distributed system with replication and automated failover, so search keeps working when a node goes down. Many large websites use it to power their search.
Key features
- Full-text, vector and geospatial search
- Distributed indexing and load-balanced querying
- Replication and automated failover
- Centralized configuration
- Docker and Kubernetes deployment options
Who it's for
Engineering teams that need a self-managed search engine for websites, product catalogs or internal documents. It suits teams that can run and tune their own servers.
Pricing and good to know
Solr is open source under the Apache 2.0 license and free to download. The project publishes binary downloads and container options, and the latest release is listed on its download page. Plan for server capacity and index maintenance when you run it in production.
