Ah, thanks, at least it's not user error :)
BTW, the Functions documentation
(http://docs.neo4j.org/chunked/1.5/query-function.html#functions-any) could
use some better wording.

Sorry about that...

Is ANY() supposed to work with array properties? e.g. I have the following
WHERE clause in my query:
WHERE pa.position AND ANY(pos in pa.positions : pos = "QB")
However, I get a syntax error "Probably missing quotes around a string"
pointed at the = sign.
I can verify that pa.positions is an arr

There are several optimizations that the shortest path algo does that

Hi guys,
I played around some more with alternative approach and it turns out the
results are not equivalent.
Since I cannot test it with the desirable max depth of 8 on my setup, I ran
a test with max depth of 4.
For a given test case, allSimplePaths returned 2 paths of length 2 and 3:

Hey Chris,
I'm happy to inform you that this is already the case :)
If you loop through the entire result, it automatically gets closed.

Ok, that previous answer was not representing my particular question thread.
My application is a new initiative, so there is no existing data store.
However, we do intent on ingesting other data sets to make our data more
interesting by our users. Some of these data sets we are interested in is

There are already (prominent) folks using Neo4j in that kind of credit card

No, we don't got that store, but we are developing new type of fraud
detection solution to CC vendor. We have one asset what they are looking,
but we like to add that real time correlation identify to solution. If we
manage to get deal, then that solution will process that amount of

Sounds great, so do you already reach those numbers?
How do you store your data today?

All of my data is interconnected and rich. This is why I like the idea of a

If your data exceeds those amounts, then polyglot persistence is probably the
way to go.
Is the other part of your data also interconnected and rich or is it just the
social part?
All that not only depends on the storage but also a lot on the use-cases and
scenarions how you are going to use t
Yes, this is true, with a few notes:
ID reuse complicates things a bit, meaning that if you delete nodes
and relationships some ids will remain unused until you restart the

is this an issue for your domain/data model?

Yes.
However, before that you will probably run into other limitations,
like file sizes, IO and RAM. That is why we are a bit careful about
just going to Longs or UUIDs.
Anything you are thinking of in particular?

Daniel,
the OSM import is loaded into its own layer corresponding to the
dataset file name as a default I think (there should be a layer node
created fro it, much in the same way as for the 'geom' index. So, if
you load that layer the same way as an index provider as you did with
the 'geom' index,
I've read that Neo4j has data capacity limitations
(http://docs.neo4j.org/chunked/milestone/capabilities-capacity.html). I
would like to confirm my understandings that the node, properties, and
relationships limitations are for each type (e.g. AND condition), not an
either/or (e.g. OR condition).
Hi Peter,
I now have a graph with the 'geom' index + testnode from the above code and
imported some OSM data afterwards. I now want to find 2 nodes by bbox query
- 550349 and 205372 (see http://dl.dropbox.com/u/18693700/graph.png). How
can I achieve this? If I query for the bbox I should at least

very cool if this worked out. Maybe you could write up a testcase that
verifies that the results are the same, and then put this as a fork to
the graphalgo package? Sounds like a great addition if this works out?
