neo4j - Cypher 2.0 - MERGE operation -


are there prereqs use merge operation? merge examples neo4j documentation such as:

merge (robert:critic) return robert, labels(robert)

return:

an unknown error occurred, unable retrieve result you.

by way, "live" examples documentation don't work either:

query: merge (robert:critic)  return robert, labels(robert) error: invalid start of query "merge (robert:critic) return robert, labels(robert)"  ^

okay, bug. opening report on github.

the following works fine btw:

start _0 = node(0) _0 merge (robert:critic) return robert, labels(robert)
