This commit ensures that SimpleText[Float|Byte]VectorValues::scorer returns null when the vector values is empty, as per the scorer javadoc. Other KnnVectorsReader implementations have specialised empty implementations that do similar, e.g. OffHeapFloatVectorValues.EmptyOffHeapVectorValues. The VectorScorer interface in new in Lucene 9.11, see #13181 An existing test randomly hits this, but a new test has been added that exercises this code path consistently. It's also useful to verify other KnnVectorsReader implementations. |

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 21.
- 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.
