Does http://localhost:7474/browser/ not support multiple unrelated queries?
This code:
MATCH (a {cond:\'1\'}), (b {cond:\'x\'}) CREATE
As a work around you can do:
MATCH (a {cond:'1'}), (b {cond:'x'}) CREATE a-[:rel]->b
WITH 1 as dummy
MATCH (a {cond:'2'}), (b {cond:'y'}) CREATE a-[:rel]->b
WITH 1 as dummy
MATCH (a {cond:'3'}), (b {cond:'z'}) CREATE a-[:rel]->b
