Add a specialized bulk scorer for regular conjunctions. (#12719) 
PR #12382 added a bulk scorer for top-k hits on conjunctions that yielded a
significant speedup (annotation
[FP](http://people.apache.org/~mikemccand/lucenebench/AndHighHigh.html)). This
change proposes a similar change for exhaustive collection of conjunctive
queries, e.g. for counting, faceting, etc.

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.
