Is there a log somewhere for instant AutoIndex?

I know where to find the logs for the BPS process when you schedule a task.  However, if you only run instant lookups it does not seem to create that same folder and structure.

So, if I am trying to troubleshoot why an instant AutoIndex is not triggering, even tho the same settings work when I schedule it, where can I look to get a clue why it is unhappy?
