Question

Azure Search .Net SDK kullanıyorum.

böyle (NOT ASYNC) işlevi, bir senkron çağırıyorum: Genellikle çalışır

var searchResults = searchIndexClient.Documents.Search<T>(searchText, searchParameters); 

. Ben herhangi bir zaman uyumsuz işlevleri kullanarak değilim, ama nedense hata sadece bir zaman uyumsuz hata gibi görünüyor var: Arama tamamlanmadan önce

System.Threading.Tasks.TaskCanceledException: A task was canceled. 

CancellationToken: IsCanceleationRequested=false 

Task: Id = 556, Status = Canceled, Method = "{null}", Result = "{Not yet computed}"

Büyük olasılıkla, istemci zaman aşımı süresi doldu. Özellikle karmaşık bir sorgu gönderdiğinizde bu hatayı görüyor musunuz? Gerekirse, search traffic analytics'u kullanarak hizmetinizdeki arama performansına bakabilirsiniz.

"Eşzamansız" bir istisna gördüğünüzün nedeni, API'nin eşzamanlı sürümünün yalnızca eşzamansız ilkellerin üzerindeki bir sarmalayıcı olmasıdır.
