Does http://localhost:7474/browser/ not support multiple unrelated queries?
http://localhost:7474/browser/
This code:
MATCH (a {cond:\'1\'}), (b {cond:\'x\'}) CREATE
You can send multiple queries to Neo4j via the cypher-shell command line tool:
cypher-shell --format plain < query.txt
where query.txt contains multiple independent queries separated by semi-colons. This also works interactively once you have started cypher-shell.
