I tried with RETURN. It returns Node. Correct node. But no node in database.
Interesting fact. When I trying to find this node using browser *MATCH n
WHERE ID(n)=11880* (id from return) it finds one node. But node is without
any property or label and colored lightgrey. But no such node in answer on
*MATCH
n RETURN n. *And after restarting Neo4j even looking with ID unsuccessful.
