How can I guarantee that a view returns the last inserted value also

1. Write a key/value using ExecuteStore command
2. I immediately try to get the last inserted value like this:
var view = _instance.GetView("all_docs", "all_docs");
view = view.Stale(StaleMode.False);
var documents = view.Select(GenerateCacheData);
