You won't see any return values from your Cypher unless you include a
"RETURN n" clause at the end of your statement. This is probably your
problem here.
On a side note, I'd strongly advise again that you do not use %
substitution and use Cypher parameters instead. You will hit problems with
unescaped characters at some point otherwise.
