neography

I need to delete all relationships between all nodes. Is there any way to delete all relationships in the neo4j graph? Note that I am using ruby bindings - the neography gem. There is no info about that in the wiki of the gem. I've also tried to find a way to do it in the neo4j documentation without any result. Neo4j version is 1.7.2. in cypher: deleting all relationships: start r=relationship(*) delete r; creating all relationships between all nodes, i'd assume: start n=node(*),m=node(*) create unique n-[r:RELTYPE]-m; but you rather dont want to have too many vertices, since it collapse on

I have a graph of the form: (products:Product)-[:in_stock { updated: timestamp }]->(stock_items:StockItem { quantity: q })-[:stored_at]->(locations:Location) Obviously more to it that that but you get the gist.

I want to search and filter by the timestamp (milliseconds since Jan1 1970) to only pull the most recent (max value) and return therefore the current quantity. I can't figure how to do that filtering. Any ideas? Consider the
