Hey guys, I'm pretty new to Neo4j, especially the indexing stuff.
Here's my situation. I want to be able to get nodes via one of their properties; in this case let's say the Nodes represent a user & I want to be able to grab a User's node via their username. So, my initial attempt may be naive (no batching etc) but I've been reading thru a a large text file (CSV format: username, userid), creating a node for each of these lines & indexing the username component. Now this needs to be unique (given that usernames are unique) so I've been using the SingleValueIndex and have run into a problem: It looks like the SingleValueIndex actually does allow multiple values for a given lookup (ex: username = phatduckk) however when trying to fetch a Node from the index that has multiples (ie: username=phatduckk was indexed twice) I get a NotFoundException with "More than one relationship xxxx" as the message. I have posted a skeleton piece of code that surfaces this problem over at: http://gist.github.com/253553 This code does not make sure that the Node being indexed for a key is always the same - it actually does the opposite: it tries to index username=phatduckk w/ a different node each time. The bit of code at http://gist.github.com/253569 does the opposite: i tries to index the same node for the index username=phatduckk each time. I also have a few random questions sprinkled in the code as comments which illustrate my noobiness =) Honestly, I'm not claiming this is a bug - I may be completely misusing and misunderstanding the indexing functionality but with my limited experience it doesn't seem that SingleValueIndex is "single" at all (hopefully - i'm just wrong and made a dumb mistake). Thanks for the help guys, Arin _______________________________________________ Neo mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
