Refer back to earlier results of a batch using the {n}
notation:
@neo.batch [:create_node, {"name" => "Max"}],
[:create_node, {"name" => "Marc"}], # Creates two nodes and index them
[:add_node_to_index, "test_node_index", key, value, "{0}"],
[:add_node_to_index, "test_node_index", key, value, "{1}"],
[:create_relationship, "friends", # and create a relationship for those
"{0}", "{1}", {:since => "college"}], # newly created nodes
[:add_relationship_to_index,
"test_relationship_index", key, value, "{4}"] # and index the new relationship
