Harden BaseDocValuesFormatTestCase (#13346) 
We hit a Codec bug in Elasticsearch, but it went unnoticed because our 
tests extend from BaseDocValuesFormatTestCase, which doesn't attempt to
read the doc-values of the same document twice. This change strengthens
BaseDocValuesFormatTestCase checks and randomly inserts that access
pattern.

Apache Lucene

Lucene Logo

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

Build Status

Online Documentation

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

Building

Basic steps:

  1. Install OpenJDK 21.
  2. Clone Lucene's git repository (or download the source distribution).
  3. 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.
