hi, I don't quite understand RelationshipIndex and RelationshipExpander. say I have a supernode city (beijing), it has 10 m users links to through relationship LIVES_IN. so how should I index? should be something like: RelationshipIndex idx = db.index().forRelationships("CITY_LIVES_IN"); idx.add(rel, "LIVES_IN", "Beijing"); if so, what's the advantage over this? Index<Node> idx = db.index().forNodes("CITY_LIVES_IN"); idx.add(user, "LIVES_IN", "beijing"); (I read source code of LuceneIndex.java, found out that the implementation of the add method is shared between Index<node> and RelationshipIndex.)
about RelationshipExpander. i don't see how RelationshipIndex could help combining with RelationshipExpander, when use GraphAlgoFactory.shortestPath(RelationshipExpander expander, int maxDepth)? thanks for help! -- Best regards Linan Wang _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
