Thanks for your answer.
Do we have any way to unlock of one process and change the mode to lock
another process?
Maybe, you understand that I use both embedded java and server process in
the same time for one application.
But my case is:
I use embedded java for application and after that
as a quick note: I have checked the query that generates the paths is
returning a valid path by testing it in the neo4j console (exact nodes id
and conditions etc)
i.e. I know the query result should deliver an itterable path when I do it
by hand.
neo4j-sh (?)$ START a=node(1418223), b=node(644
Hi All,
when using an Iterator from an execution result I sometimes never get a
return from the iterators .hasNext() method.
If I try to debug it by dumping the exectutionresult to a string then the
result is consumed so I never hit the the error.

Hi,
I am seeing the same problem. I had my database created by neo4j version
2.0.3. It was working perfectly fine.
I installed Gephi which was unable to load my database. After that I am
unable to start my neo4j using that database.
Were you able to resolve your issue?

I'm developing an social app that requires the user's Facebook friends list.

updating the list to my Neo4j DB.
For each friend on the user's list, I want to first see if the friend is in

Hi Rick
usually it is not recommended to start the server from Java,
you install and start it as a normal database service on your operating system.

Also in terms of growth, even if your db size is 10x or 1000x larger, you won't
have all that data as active / hot state.
So the comparison might not be do what you intent to.
You might want configure the JVM setting that dumps the heap on crash and

On console.neo4j.org or rather neo4j-console-19.herokuapp.com you can use the
node_auto_index which is automatically populated.
Perhaps you can share your create script.
Perhaps you should do a query that lists all relationships and their end nodes

It will faster to just let the matcher do it's job.
It will only aggregate on n.UID, r.name
(don't know what r.name is)
please note that count(*) counts the total rows generated by the matcher, not

Perhaps it makes more sense to handle your subtypes with labels instead?
And I'd love to see a picture :)
NEGATION is alway tricky to handle.

You can work around it by having a conditional loop (FOREACH) around these,
something like:

hi,
i'm green hand. I want to compare advanced mapping with simple mapping
way. But when call persist method, throws a exception as following
Exception in thread "main" java.lang.ClassCastException:
com.baidu.rigel.neo4jTest.domain.World cannot be cast to
org.springframework.data.neo4j.
You have to loop over the traverser, otherwise it won't be executed. Traversals
are lazy in Neo4j.

Hmm interesting.
Can you return two of the different nodes side by side?
Do you only have movies in your db?

No, we don't.
It also depends on your use-case how it shows up.
The performance difference is due to a different cache implementation which is
more memory efficient and GC friendly.

You can also store a phonetically reduced stem of the word as additional

Oh... It does not work with embedded graph.

Hi Tatham,
thank you for your answer.
Well, I must accept your answer, either it seems a little but illogical to
me (why more than one only for nodes but this is philosophy).
Just as a further help from you, it is possible

2) to filter labels in a query us
Alex,
you can only lock the physical DB directory to one of your two processes
(Embedded Java, Neo4j Server) at a time. Eitehr start the server and access
the DB via REST against the server and the Cypher endpoint, see
http://docs.neo4j.org/chunked/stable/server-java-rest-client-example.html#_sendi
So,
looking at Soundex, you are not actually looking for an an Arabic stemmer
like
http://lucene.apache.org/core/3_6_0/api/all/org/apache/lucene/analysis/ar/ArabicAnalyzer.html
but a way to correlate English and Arabic words by their similarity?

I am a learner of Neo4j and used in one of the financial project.
Is there a way where I could query my Neo4j to identify similar names
(mainly for identifying spelling mistakes), and later on I could merge
those records.
Few sources says; using Soundex or other related algorithms would help.
