How do I report on nodes with multiple labels
If your data model has chosen to define multiple labels on a node, for example
create (n:Actor:Director {name:'Clint Eastwood'})
To find all nodes which are defined with both labels of Actor
AND Director
use the following Cypher:
match (n) where n:Actor and n:Director return n;
Using this syntax will be performant as it will start with a NodeByLabelScan
If you need to find all nodes which have either label of Actor
OR Director
use the following Cypher:
MATCH (n:Actor) RETURN n UNION MATCH (n:Director) RETURN n
Using this syntax will be performant as it will perform a NodeByLabelScan
on both the Actor
label and the Director
label and then merge the results.
