I think you have to create a custom RelationshipExpander, that takes a list
of pairs of type and direction and checks at the current path length for
the correct combo to look for.
I think from a quick look that org.neo4j.kernel.OrderedByTypeExpander
already does this btw. Please check.
new
OrderedByTypeExpander(asList(Pair.of(DynamicRelationshipType.withName("preferred_store"),
Direction.OUTGOING),Pair.of(
DynamicRelationshipType.withName("preferred_store"),
Direction.INCOMING), ....)
