Hi,
I have the following attached graph where I have persons who traveled to
some cities.
What I want to find out is, for a given city, for instance Toronto, "the
ones who traveled there, also traveled to these other cities" (in the
attached graph are Tokyo (by Adriano) and Paris (by Peter)).

Hi everyone,
I was playing right now with the index api to do some fulltext search, and I
found something what I think is not good for the API.
The index API rely heavily on Strings, just like the following:
Index typeIndex = index.forNodes("places");
I do write the call to forNodes method a

Hi Jim,
We (Adriano and Jose) wrote the Restfulie example and it is already
published on the wiki. Thanks for the attention. It is the basic doc, just
like the rest-client one.
Thanks

Hi Anil,
if you're also interested, there is the IMDB example:
https://github.com/neo4j-examples/imdb. Also I have an example project at my
github: https://github.com/adrianoalmeida7/neo4j-vraptor-example where I
integrate Neo4j with a webframework other than SpringMVC (in this case,
VRaptor). I a
I'll put some cons, but the pros are just the opposite for the other.

that you're attached to JRuby and maybe you want/have to use plain MRI,
Rubinius or something else.
- One con that I can think on the REST API is netwo
I agree with Marko.
In fact, I'd say that if you can choose more than one option, I'd go with
option 1 and 2. The option one when you're not sure you're creating a loop
(not sure if the end node will be the start node), so in order to avoid ifs
on the client code, option 1 will go for it. If you'r
Yep,
the neo4jserver is just a rest api over neo4j database, so it's still stored
in at the disk. So, all you need to do, is to point your java application to
the neo4j db directory.
Remember, that you'll be unable to start both you app and the neo4j server
at the same time, at the same database.

Hi,
I've been doing some stuffs with the Cypher API on M4 and found a couple
strange issues at the API, that I'd like to discuss.
- CypherParser.parse("") method throws SyntaxError, which is a checked
exception. 2 issues here.
a) a checked exception called Error, seems weird and going against

Paul,
Did you try to upgrade to 1.2, then to 1.3 and then to 1.4 before going from
the 1.1 straight to the 1.4?

I've sent a Pull Request long time ago fixing this, but it was to the old
neo4j repository. Guess it wasn't merged.
https://github.com/neo4j/graphdb/pull/2
Can send it again, if the guys want.

Hi Edgard,
sure you can do a FullText Search on your data with Lucene and Neo4j. Did
you take a look here
http://docs.neo4j.org/chunked/1.4/indexing-create-advanced.html
If you need any other help, just let us know.

Hey Nuo,
wrapper.java.maxmemory and Xmx won't help, since it is a PermGenSpace
problem, and they only deal with HeapSpace. Did you try with: -XX:*MaxPermSize

Anyway, something very wrong is happening, since you have few nodes.
It is happening only on production, or development also? If it i
Hi Allison, just adding,

Hi Dima,
and regarding your second message, the NotFoundException for the phone
property, what happens is that, on the beginning you had some nodes without
the phone property, and some time after, nodes were created with this phone
property, and that's a good thing, each node can have it's own pro

With cypher you can do:
start a=(10) match a-[:FOLLOW]->b-[:FOLLOW]->a return a
where 10 can be your node Id or you can either use an index.

Hi Filip,
if you need only those nodes who have the Geemente property, you can specify
it on the where clause. Example:
where a.Geemente and a.Geemente = 'Antwerpen'
with this, the verification for Antwerpen (lovely city, BTW) is only
executed if Geemente property exists on a node.
