A $in query with multiple index choice and empty result is much slower after 6.3 upgrade, from the explain output we can tell that the problem is from SBE multi-planner. One of the predicate is an empty $in predicate descriptionRef:{ $in: []}{}, we should think about whether there's anything we can do to improve the performance of the multi-planner in this scenario.
