When I'm in the Nest Client, I use `Client.SearchAsync<Entity >()` , Some fields in the result are Null, Entity is the Index structure that I inserted. When I use `Client.SearchAsync<object>()`, I don't want to use Object, which means I have to do one more serialization. Would you please tell me why
