README.md

Apache Lucene

Apache Lucene is a high-performance, full-featured text search engine library written in Java.

Online Documentation

This README file only contains basic setup instructions. For more comprehensive documentation, visit:

Latest Releases: https://lucene.apache.org/core/documentation.html
Nightly: https://ci-builds.apache.org/job/Lucene/job/Lucene-Artifacts-main/javadoc/
Build System Documentation: help/
Developer Documentation: dev-docs/
Migration Guide: lucene/MIGRATE.md

Building

Basic steps:

Install OpenJDK 17 or 18.
Clone Lucene's git repository (or download the source distribution).
Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.

See Contributing Guide for details.
