Hi all, I'm just starting using neo4j, and I'm having a few problems finding all the details of what information is able to be extracted from paths in neo4j. In particular, for the shortestPath and kShortestPaths algorithms, I seem to only be able to...

Finally found that the apoc shortest path algorithm returns the relationship information I want: MATCH (start {REFERENCE:'NB7864'}), (end {REFERENCE:'NB4642'}) CALL apoc.algo.dijkstra(start, end, 'FibreConnection','weight') YIELD path, weight RETURN ...

Yes - I don't think that solution is correct. I suspect I'm rematching against the entire graph, which means I could pick up extraneous relations. I've tried returning path, but all it seems to contain is the cost property which I'm passing in as wei...

Just another question relating to using labels - I have several elements in the domain all of which can be in a path - namely buildings, enclosures, hubsites - and probably few others later. Is it worthwhile creating a separate label that encompasses...

I'm now thinking I need to look into the cypher projection, and nodeQuery and relationshipQuery to solve this issue.

Actually, I put an index on REFERENCE that I hoped would do the trick.
