Description

The slice allocation method allocates one thread per segment today. If a user wishes to use a different slice allocation algorithm, there is no way except to make a change in IndexSearcher. This Jira proposes an interface to decouple the slice allocation mechanism from IndexSearcher and allow plugging in the method from an external factory (like Collectors).
