The filter example text doesn't include the unmanaged/external number -> name mappings.
Do you still need them or did you figure it out yourself?
I flipped a 'select distinct status from nodes' and got them (9 = unmanaged, 11 = external). You know how we roll.
I was showing filtering to a customer and about the time I said "here are all the numbers you'll need" I had to punctuate with "err, except for these two."
