In what scenario would you "have" a Node which weren't stored in the db? Nodes are created inside a transaction and if that transaction committs the node is stored in the db. > > indexService.index( node, partIndexName, value ) can add node to db, but I > may don't need specify the index as I can specify the index by annotation > declaration in a POJO. > > IndexService is the old index API, look at the integrated index > API<http://wiki.neo4j.org/content/Index_Framework>instead. Associating a > key/value pair with a Node in an index doesn't add that node to the database, it just adds that key/value pair to the index and associates it with the given Node. The nodes already exist in the database by that time (or were created in the same transaction that you're currently in). Are you writing your own layer in top of Neo4j with @Annotations? Have you looked at jo4neo <http://code.google.com/p/jo4neo/>? > > > Regards, > > Caron > > > > > > _______________________________________________ > Neo4j mailing list > User@lists.neo4j.org > https://lists.neo4j.org/mailman/listinfo/user > -- Mattias Persson, [matt...@neotechnology.com] Hacker, Neo Technology www.neotechnology.com _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
