Hi Rafael, I am not too hands on with these problems, but others here are. however, I see two ways to do what you want:
1. Neo4j Traverser -------------------------- Using the Neo4j Java API, you could do an exhaustive search for J -(knows)-> P -(friends)-> M and have a custom ReturnableEvaluator, much like in http://wiki.neo4j.org/content/IMDB_Finding_the_Path that checks if these two relationships are present on the current node. 2. RDF ---------- Using SparQL, http://www.w3.org/TR/rdf-sparql-query/, and the Neo4j RDF components http://components.neo4j.org/, you could build up a RDF graph and ask that one with SparQL. Quite unneccesary for this use case IMHO but it probably would work.
