Why not just add a "deleted" attribute to a resource, set this to
be "true" when a resource is deleted, and then automatically add
"!deleted" to search queries?

   Of course you will build an index.  That's the problem, because you are
   locating the data without traversing the collection hierarchy to find the
   data.  Let's say you find a hit using that index.  That item may actually
   have been deleted because you have deferred garbage collection, and there is
   no way to update the index to remove that item until the actual resource has
   been deleted.  If you were traversing the hierarchy as well, you wouldn't
   find that item if it would be garbage collected later because there wouldn't
   be a path to find it.
