Correct.  This node knows that it has no neighbors, so it
knows that nothing was flooded.  But if you don't want to
do anything special and wait for the some timer to expire,
that would be fine too.

You should say something like "Search result set was empty.
There is nothing to GET" or "Search result set was empty.  [1] was
not a valid file identifier."
