Examples of org.neo4j.graphdb.index.IndexManager

org.neo4j.graphdb.index.IndexManager
A one stop shop for accessing {@link Index}s for {@link Node}s and {@link Relationship}s. An {@link IndexManager} is paired with a{@link GraphDatabaseService} via {@link GraphDatabaseService#index()} so thatindexes can be accessed directly from the graph database.
