Question

我不确定问题是什么，但我必须做错事，因为索引为空，即使我删除了where b.Status == ...行。有什么想法吗？

public class Bookings_ToBeScheduled : AbstractIndexCreationTask<Inspection, BookingRequest>
{
    public Bookings_ToBeScheduled()
    {
        Map = inspections =>
            from i in inspections
            from b in i.Bookings.Values
            where b.Status == BookingStatus.Requested || b.Status == BookingStatus.InspectorAssigned
            select new
            {
                InspectionId = i.Id,
                i.InspectionType,
                b.BookingNumber
            };
    }
}

试试这个，而不是：

public class Bookings_ToBeScheduled : AbstractIndexCreationTask<Inspection, BookingRequest>
{
    public Bookings_ToBeScheduled()
    {
        Map = inspections =>
            from i in inspections

            select new
            {
                InspectionId = i.Id,
                i.InspectionType,
/*
 BookingNumber = i.Bookings.Values
          .Where(b => b.Status == BookingStatus.Requested || b.Status == BookingStatus.InspectorAssigned)
          .Selcet(b=>  b.BookingNumber)

*/
                BookingNumber = from b in i.Bookings.Values
                                where b.Status == BookingStatus.Requested || b.Status == BookingStatus.InspectorAssigned
                                select b.BookingNumber
            };
    }
}

通常最好不要在索引中拥有扇出（每个文档有多个条目）。我不确定哪个版本的BookingNumber会起作用，Linq方法肯定会有用。
