About Apache Solr
Apache Solr is an open-source, standalone search platform built on top of Apache Lucene, adding a REST API, distributed search, faceting, and administrative tooling that Lucene alone doesn't provide. It's a common choice for enterprise and application search, and remains actively used alongside more recent alternatives like Elasticsearch and OpenSearch, both of which are also Lucene-based under the hood.
Apache Solr Lifecycle Explained
Solr's own documentation lays out a simple, three-tier policy: the current major version gets frequent feature releases, the previous major version gets occasional critical security or bug fixes only, and everything older is considered end of life with no further updates. As of the current release cycle, Solr 10 is the actively developed version, Solr 9 is the previous major still receiving occasional critical fixes, and Solr 8 and earlier are all fully end of life.
Frequently Asked Questions
Is Apache Solr end of life?
Not as a project. Solr 10 is under active development, and Solr 9 still receives occasional critical fixes as the previous major version. Versions 8 and earlier are end of life.
What is the latest version of Apache Solr?
Solr 10.0.0, released in March 2026, is the current major version. Solr 9.10.1 is the latest release in the previous, still partially supported major line.
What is Apache Solr?
Apache Solr is an open-source search platform built on Apache Lucene, providing full-text search, faceting, and distributed indexing through a REST API, commonly used to add search functionality to websites and applications.
Why use Apache Solr?
Solr is a mature, purpose-built search platform with strong support for structured, faceted, and Boolean search, and an established ecosystem of managed services and tooling. Community discussion suggests demand has remained steady even as alternatives like Elasticsearch have grown, with users often citing Solr's search-first design as a reason to prefer it over datastore-first alternatives.
