    Relationship relationship = getRelationshipByIRI(filter.iri, workspaceId);
    checkNotNull(relationship, "Could not find edge with IRI: " + filter.iri);
    edgeIds.add(relationship.getIRI());
    if (filter.includeChildNodes) {
      Set<Relationship> childRelations = getRelationshipAndAllChildren(relationship, workspaceId);
      edgeIds.addAll(childRelations.stream().map(Relationship::getIRI).collect(Collectors.toSet()));
    }
  }
  query.hasEdgeLabel(edgeIds);
}
