It is used to build full-text search, faceted navigation, document search, e-commerce search, and search-backed data applications.\n\n## Who is Apache Solr for?\n\nSolr is suitable for developer teams that need a configurable, self-managed search engine and have the operational capacity to run it. It is common in enterprises, content portals, libraries, commerce systems, and applications with demanding search requirements.\n\n## Key features\n\n- Full-text search based on Lucene.\n- Faceting, filtering, highlighting, and spell checking.\n- Distributed search and SolrCloud for scaling.\n- Flexible schema and indexing configuration.\n- Rich query features for search-heavy applications.\n- Open-source ecosystem and mature documentation.\n\n## Pros and cons\n\n### Pros\n\n- Mature open-source search platform.\n- Strong configuration options for relevance and indexing.\n- Good fit for complex search experiences.\n- No license cost for the core software.\n\n### Cons\n\n- Requires operational knowledge to run well.\n- Schema and relevance tuning can be time-consuming.\n- Managed hosted search services may be faster for small teams.\n\n## Pricing and costs\n\nApache Solr is open source. Costs depend on infrastructure, hosting, operations, support, monitoring, and the time needed to tune indexing and relevance.\n\n## Alternatives to Apache Solr\n\n- **Elasticsearch:** Distributed search and analytics engine with a large ecosystem.\n- **Amazon OpenSearch:** Managed AWS service based on OpenSearch.\n- **Algolia:** Hosted search API for fast product and app search.\n- **Meilisearch:** Lightweight open-source search engine.\n- **Azure AI Search:** Managed search service in Azure.\n\n## FAQ\n\n**Is Solr still relevant?**  \nYes. Solr is mature and still used in many production search systems, especially where teams need deep search configuration.\n\n**Is Solr easier than Algolia?**  \nUsually no. Algolia is simpler to start with, while Solr gives more control but requires more operational work.\n\n**Can Solr scale?**  \nYes. SolrCloud supports distributed indexing and querying across clusters."
