This example is creating a graph of the characters in the Matrix via the shell and then executing Cypher queries against it:
Neo4j is configured for autoindexing in this case with
node_auto_indexing=true node_keys_indexable=name,age relationship_auto_indexing=true relationship_keys_indexable=ROOT,KNOWS,CODED_BY
in the neo4j configuration file.
The following is a sample shell session creating the Matrix graph and querying it.
