Monitor to support search concurrency

[javanna]

Description

There is currently no way to provide an executor to the index searcher used internally by monitor.

There may be value in parallelizing execution, but besides exposing the ability for users to provide an executor like we do with ordinary search, a refactor is needed to properly support inter-segment concurrency in monitor.

Hi, I’m interested in working on this as a first Lucene contribution.

I noticed that #16197 removed deprecated search(Query, Collector) usages from the monitor module.
Is there a recommended next step for adding executor/concurrent search support to monitor, or a smaller part of this task that would be good to start with?

Hello @offsetflow this looks to be a good mentored project, but perhaps too broad for a first lucene contribution. It requires some knowledge of how search concurrency works, as well as the monitor module and how it could leverage search concurrency to speed up its execution. I would recommend looking instead for good first issues if you want to start contributing to Lucene. Good luck!

Thanks ! I'll look for some good first issues and spend more time getting familiar
Appreciate the help!
