This adds a new, ground-up implementation of faceting that computes aggregations while collecting. This has the following advantages over the current faceting module: 1. Allows for flexible aggregation logic instead of just "counts" in a general way (essentially makes what's available in today's "association faceting" available beyond taxonomy-based fields). 2. When aggregating beyond "counts," association value computation can be expensive. This implementation allows values to be computed only once when used across different aggregations. 3. Reduces latency by leveraging concurrency during collection (but potentially with increased overall cost). This work has been done in the sandbox module for now since it is not yet complete (the current faceting module covers use-cases this doesn't yet) and it needs time to bake to work out API and implementation rough edges. --------- Co-authored-by: Egor Potemkin <epotyom@amazon.com> Co-authored-by: Shradha Shankar <shrdsha@amazon.com> Co-authored-by: Greg Miller <gsmiller@gmail.com>

- Nightly: https://ci-builds.apache.org/job/Lucene/job/Lucene-Artifacts-main/javadoc/
- New contributors should start by reading Contributing Guide
- Build System Documentation: help/
- 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.
