Currently there is no indication in the log file for slow query entries that the target of the operation is a view.  This can be very confusing since, for example, the operation could report using an index for a field that is seemingly not used or have a sort when none is requested directly.  

We should indicate when the target entity is a view.  Such an indication could range from a simple boolean (eg isView:1) to something more complex like reporting the final generated pipeline (as is done when explain is used on such queries).
