index
A structure over a propertyA named value stored on a node or a relationship.. The database reads it to find nodesA vertex in a graph. In a property graph it can carry labels and properties. or relationshipsA named, directed connection between two nodes. Every relationship has a type, a start node and an end node. by property value, rather than scanning every one.
Also written: indexes
Example
An index over the title property of every (:Movie).
cypher
CREATE INDEX Movie_title IF NOT EXISTS
FOR (m:Movie) ON (m.title)MATCH (m:Movie {title: 'Toy Story'}) reads the index and goes straight to that node. Without the index, the database reads the title of every (:Movie) in the graph to find it.
