Adrien Grand 398c7e1f5c Enable rank-unsafe optimization of top-k hit computations by quantizing scores. 
This adds a `ScoreQuantizingCollector`, which quantizes scores with a
configurable number of accuracy bits. This allows dynamic pruning to more
efficiently skip hits that would have similar scores. While this should be
considered rank-unsafe since top-hits are different compared to running the
top-score collector on its own, it's worth noting that top hits are correct in
quantized space.

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 17 or 18.
  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.
