As I understand it, Ticket 273 outlines an issue with searching for tombstone entries after successfully setting up a replica (which as far as I'm hearing, we haven't done). And ticket 274 concerns indexing the tombstone entries. I am able to search for tombstone entries (http://pastebin.com/raw.php?i=a4ytYZvt) and don't see the errors specified in ticket 274.
