commit() only guarantees documents are persisted to the Directory; an already-open IndexReader only picks up the change according to its ReloadPolicy. With the default OnCommitWithDelay, the reload happens asynchronously on a background thread and is not guaranteed to be done by the time commit() returns, on any Directory implementation (including RamDirectory), so a search immediately after commit() can still miss the documents just committed. Document this explicitly on ReloadPolicy::OnCommitWithDelay, IndexReader::reload(), and IndexWriter::commit(), and add a runnable example showing the ReloadPolicy::Manual + explicit reader.reload() pattern for deterministic read-your-writes.
