When an executor is provided to the IndexSearcher constructor, the searcher now executes tasks on the thread that invoked a search as well as its configured executor. Users should reduce the executor's thread-count by 1 to retain the previous level of parallelism. Moreover, it is now possible to start searches from the same executor that is configured in the IndexSearcher without risk of deadlocking. A separate executor for starting searches is no longer required. Previously, a separate executor was required to prevent deadlock, and all the tasks were offloaded to it unconditionally, wasting resources in some scenarios due to unnecessary forking, and the caller thread having to wait for all tasks to be completed anyways. it can now actively contribute to the execution as well. -- This is an automated message from the Apache Git Service.
