MultiCollector shouldn't report that scores are needed when they're not. (#12083) 
When sub collectors don't agree on their `ScoreMode`, `MultiCollector`
currently returns `COMPLETE`. This makes sense when assuming that there is
likely one collector computing top hits (`TOP_SCORES`) and another one
computing facets (`COMPLETE_NO_SCORES`) so `COMPLETE` makes sense. However it
is also possible to have one collector computing top hits by field (`TOP_DOCS`)
and another one doing facets (`COMPLETE_NO_SCORES`), and `MultiCollector`
shouldn't report that scores are needed in that case.

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.
