# Description This change allows users to sub-class `DrillSideways` and override the logic for creating a "drill down" `FacetsCollector`/`FacetsCollectorManager`. This is useful if the user doesn't want to collect for drill downs (e.g., they can provide `null`), or if they're already collecting for drill downs in a custom `Collector`/`CollectorManager` that's already being provided to `search`. In the latter case, they may want to override these methods to return `null` so they don't wastefully collect for drill downs twice (once in their customer collector and again internally to `DrillSideways`). # Solution `DrillSidewaysQuery`/`DrillSidewaysScorer` already support a `null` drill down `FacetsCollector` so this is as simple as modifying `DrillSideways` itself. I added `protected` methods for creation of the drill down collectors, allowing sub-classes to override. # Tests Added new tests to test a sub-classed `DrillSideways` that provides `null` collectors. # Checklist Please review the following and check all that apply: - [x] I have reviewed the guidelines for [How to Contribute](https://wiki.apache.org/lucene/HowToContribute) and my code conforms to the standards described there to the best of my ability. - [x] I have created a Jira issue and added the issue ID to my pull request title. - [x] I have given Lucene maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
