In most places, an empty string passed for a term acts as a special
"virtual" term which indexes all documents, but not for
replace_document() or delete_document().  I think this inconsistency is
probably better than removing all existing documents if someone passes
in an empty string by mistake to either method, though I don't think
it is actually the result of a deliberate decision.

So it isn't currently valid, but Xapian will throw an exception if you
try to do it, so there's probably not a lot of point duplicating that
