Beginning Neo4j Chris Kemper
Publisher: Apress

By simply putting CYPHER 2.2 at the beginning, that particular query will be parsed with the 2.2 version of the parser. Beginning Neo4j is your introduction in the world of graph databases, and the benefits they can bring to your applications. First, i enable node auto index and relationship auto index in neo4j.properties, and add property key person_name,hotel_name for node. These functions all operate on string expressions only, and will return an error if used on any other values. First, download and unzip Neo4j, change into the new directory and start the server. For a short introduction, see Section 8.1, “What is Cypher?”. It was working fine just at org.neo4j.kernel.impl.nioneo.store. The Cypher part is the authoritative source for details on the Cypher Query Language. I think, many people would like to build an Railsapp with this new Database. Got following layout in my neo4j db: a / | \ b c d / \ | e f g | / \ h i j . Py2Neo version of cypher query in python from py2neo import neo4j p = shortestPath(beginning-[* 500]-end) \ RETURN p" result = neo4j. Having extremely bad performance results with using cypher we are beginning to question whether Neo4J is the right tool for this problem. Taking the first steps with Neo4j? What I' d like to do is to query for all child nodes e.g. I am getting following error while I start my neo4j in my production environment. Read our introductory tutorials and developer guides that cover all areas of your development lifecycle. I'll start by saying that I'm not announcing yet another new open source project.
