[Orgmode] Question about searches (ultimately for agenda)

[Mueen Nawaz]

Hi,

In the docs (10.3.3 Matching tags and properties), I see ways to do tag 
searches that can also search TODO states.

Can I also search TODO levels? For example, in one file covered by the 
agenda, I use the usual DONE to denote done. In another, which is 
focused on simply stuff that I have borrowed/lent, I have RETURNED as my 
"DONE" state.

I occasionally apply tags to headings with the name of the person 
involved. So let's say that I've put :Jack: on some headings of items 
that have been lent and returned. But I also have :Jack: in my other 
.org files that are not about lending/borrowing.

I want to search for all headlines that have :Jack: in them, but exclude 
anything that is a "DONE" state - so exclude both DONE and RETURNED.

I know I can just do:
Jack-TODO="DONE"-TODO="RETURNED"

But I don't want to keep editing it as I change my DONE states or add 
more DONE states.

Is this possible?

Thanks.
