Backport of #12160 --------------------------------------------------- ### Description Issue #11862 ### Solution `AbstractKnnVectorQuery` currently performs HNSW searches (one per-segment) iteratively Since this is done in a single thread, we can make it concurrent by spinning off per-segment searches to different threads (and make use of available processors) The actual search is performed in `Query#rewrite`, and support to allow concurrency there was added recently (#11838) by passing an `IndexSearcher` (which wraps an `IndexReader` and `Executor`) Proposing to achieve this by `CompletableFuture`: - If the `Executor` is not set, we can perform a blocking call to `CompletableFuture#completedFuture` - Else we submit the task of per-segment search to the `Executor` using `CompletableFuture#supplyAsync` -- This is an automated message from the Apache Git Service.
