I think I'm asking the correct question - I had downloaded updates and Logos was indexing. Out of habit, I just manually put my machine to sleep and then realized this thing was indexing (again, I think that's what it's called).
I awakened the unit, closed down Logos and booted it back up again, but there is no indexing. It was only about 3% along when I put it to sleep.
The question for this month is - how do I index manually?
