Emil, there are some good docs at http://docs.neo4j.org/chunked/snapshot/tutorials-java-embedded-traversal.html#_new_traversal_frameworkthat you can use.
In your case, you are stopping the traversal but not excluding the nodes you find from being part of the result. It seems you are using the first version of the Traversal framework, where there is not only a StopEvaluator, but even a ReturnEvaluator that determines what to return. Alternatively, have a look at Cypher ( http://docs.neo4j.org/chunked/snapshot/tutorials-cypher-java.html from Java) with the LIMIT keyword, see http://docs.neo4j.org/chunked/snapshot/query-limit.html) HTH Cheers, /peter neubauer G: neubauer.peter S: peter.neubauer P: +46 704 106975 L: http://www.linkedin.com/in/neubauer T: @peterneubauer Neo4j 1.6 released - dzone.com/6S4K The Neo4j Heroku Challenge - http://neo4j-challenge.herokuapp.com/ On Wed, Feb 8, 2012 at 10:58 AM, Emil Dombagolla < em...@hsenidoutsourcing.com> wrote: > Hi all, > > Please help me. > > I user Traverse API .
