What version of Neo4j are you using? This query is valid syntax for 1.4.x and
1.5.M01.
Later you would want to use:
> start a=node:nodeIndex(identifier='0') return a
And if you do in Java:
Node node = gds.index().forNodes("nodeIndex").get("identifier","0").getSingle()
then node is the user you want?
I'm not sure if that makes a difference, did you index your identifiers as
Strings or numeric values?
Cheers
