The former shared repository for Apache Lucene and Apache Solr, open-source search software. Lucene and Solr have split into separate top-level projects, so this repo only hosts maintenance for the 8.11.x branch.
Use cases
- add full-text search to a Java application
- build a faceted search engine over large document collections
- index and query millions of documents with ranking and highlighting
- run a self-hosted search server like Solr
- implement spellchecking and autocomplete for search
When to choose
- you need battle-tested, high-performance full-text indexing and search on the JVM
- you want the search core used by Solr, Elasticsearch, and OpenSearch
- you need mature tokenization, highlighting, and faceting capabilities
When to avoid
- you want to contribute new code - use apache/lucene or apache/solr instead
- you need a lightweight embedded search for small datasets
- you prefer a managed or non-JVM search stack
