Yes, why not? I assume that is a 1:1 relationship.

Hi Nicola,
it could be that the database was created with Neo4j 2.0-M06 and there were
changes in RC1 in terms of the label indexes.
Thanks for the heads up, I'll have a look and update it to 2.0.1

But you should already get paths back?
Can you describe your graph shape? Remember cycles don't work well there.
Could you update your version to 1.9.6 or 2.0.1 ?
I think you could use a custom PathExpander that just doesn't return anything
anymore or throws an exception when a certain time
Oh and btw. I would LOVE to see a blog post from you about what you're working
on!
Thanks so much

Dear all,
After, as it seems, a clear restart of the Neo4j server (running before
smoothly for several months) *the web interface's dashboard suddenly
started to show absolutely wrong counts*, i.e.:
Before restart: nodes - ~600 (!), relationships - ~50k, etc.
After restart: nodes - ~122k

I have an abstract class OrganisationNode containing a @GraphId id

I have several concrete classes extending OrganisationNode, for example

If I put another @GraphId id field on InstitutionNode, I get the
Wow this is great! I'll definitely try what you did. Please expect
questions along the way.
And a write-up is coming; I was thinking I'd do that as soon as I get some
relationships in, but now I should probably make a post about LOAD CSV.
I'll post a link when I do.
Thanks!

Well, that's the point - no massive deletes of nodes at all. Total number of
nodes *never* went over ~650, and for relationships - over ~60k. There was
once a removal of ~5k of relationships though, but this can not explain the
jump of 50k - 150k.

I am running a neo4j query from a .cql file using the following command:

However the results insided result.txt are wrapped with '-' and '|' marks
that makes it hard to post-process. Is it possible to have the neo4j shell
not put these marks?
Hey Nikolay,
So this is an interesting query: the thing that stands out the most to me
is that this query isn't doing anything with relationships - it's not
taking advantage of the graph. So all that's left for Neo4j to do is to
begrudgingly walk through every single Book and put them in order

Hi,
How can I load my database with multiple processes?
This is my init function:

if (graphDb == null)

Perhaps as a concrete example of what Chris is describing here, I can
comment further.
The original example had three properties to order on, isbn, titel,
pubDate. The text 'and so on' implies more, but let's assume there are not
too many more. If there are indeed a limited number of predictable
Hi Tom,
I did exactly what you did (on MacOS) and it worked out of the box, could you
perhaps retry on an empty db?
What OS are you using?
LOAD CSV FROM http://www.ophileon.com/neo4j/eurovoc_terms.csv; AS csvLine
CREATE (t:Term { id: toInt(csvLine[0]), name: csvLine[1]});
Great answer, I want to second that.
Esp. when sending in the last place in the chain where you want to continue.
New syntax would be this and I would also add the limit directly to the
path-expression (unfortunately not possible as parameter
MATCH p=(n)-[:next*20]-(x) WHERE id(n) = {prev_id}
Only one active process at a time can access the storage files.
What do you want to do?

You're not expected to override exists.
It should actually just work. I would appreciate a JIRA issue with the content

If you import them all at once you should have larger transaction sizes,
anything from 1000 to 5 elements per transaction.

You can send your cypher query to the http endpoint and get the json back if
that helps you.
Otherwise if you want to have other outputs, perhaps you are interested in my
