Using MATCH and OPTIONAL MATCH

The MATCH keyword allows you to specify the graph traversal patterns to find and return the data from Neo4j. It is most often coupled with a WHERE clause to filter out the results, and a RETURN clause to return the results.

  • This shows a basic MATCH query that will find all nodes in the database and return them. It will also return all the node properties shown as follows:
    MATCH (n)
