-To aid query performance, you can add indexes to your data.
-(The dataset you create in this guide is very small, but it is good practice to use indexes as they can greatly improve query performance when the datasets are larger.)
-
-In this small dataset, you are mainly interested in names of people and titles of movies.
-Run the following to add indexes on these properties
-
-[source,cypher]
-----
-CREATE INDEX person_name FOR (p:Person) ON (p.name);
-CREATE INDEX movie_title FOR (m:Movie) ON (m.title)
-----
-
-Note that you can also add constraints to your data to ensure uniqueness for example.
-Adding constraints automatically adds a correpsonding index.
-See link:https://neo4j.com/docs/cypher-manual/current/constraints/[Cypher Manual -> Constraints^] for more information.

 In the next step, you will look for nodes and their properties.
