Frank,
Do you have a minimal test case reproducing this?

 I *think* that what I need is to do is this:

 Relationship relationship = relationshipIndex.get(signature, signature,
 lastNode, null).getSingle();

 If I understand the documentation correctly, this should return only the
 relationships attached to the node lastNode that have the value I'm
 asking for.

 Unfortunately, my attempt to use this function results in the following
 exception:

 java.lang.UnsupportedOperationException
at
 org.neo4j.rest.graphdb.index.RestRelationshipIndex.get(RestRelationshipIndex.java:42)

 I'm kind of stuck at this point. Any ideas?

The function I'm calling isn't implemented. I found it in the source code:

public class RestRelationshipIndex extends RestIndexRelationship
implements RelationshipIndex {
public RestRelationshipIndex( RestRequest restRequest, String
indexName, RestAPI restApi ) {
super( restRequest, indexName, restApi );
}

public ClassRelationship getEntityType() {
return Relationship.class;
}

public org.neo4j.graphdb.index.IndexHitsRelationship get( String s,
Object o, Node node, Node node1 ) {
throw new UnsupportedOperationException();
}

public org.neo4j.graphdb.index.IndexHitsRelationship query( String s,

Ok, thanks for pointing that out, I was not aware that it was missing.

Will add the implementation.

[Neo4j] Relationship indexes

2011-12-02 Thread Frank 
I'm having some trouble understanding relationship indexes.

I plan to have nodes with many (hundreds, sometimes thousands) of
relationships to other nodes.

Give node N, I want to be able to quickly locate one of those relationships
given a key. I want to consider only the outgoing relationships of that
node, not all nodes.

Can this be accomplished? The problem I'm seeing is that when I try to look
up a relationship from a RelationshipIndex, I don't see how to limit that
lookup to just the outgoing relationships of one node.
