[Neo4j] Neo4j.py 0.2
Hi all, where can I find a python binding for neo4j equivalent to last neo4j java version. my problem is that the database was created in neo4j java latest version, and when accessing the index in python 0.1 snapshot it gives me a version conflict error. one more question, is lucene fulltext search implemented in python version? THX in advance. Francois. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
[Neo4j] Eigenvector Centrality subclasses
Anyone know the pros/cons of the Arnoldi eigenvector centrality implementation over the Power implementation? I see that Arnoldi gives a little more information on number of iterations, but it seems neither is deterministic.

[Neo4j] Neo4j REST Server with path prefix
Hi all, how can I setup the REST server to use a standard url path prefix?

[Neo4j] Question about setConfiguration()
Hi Mattias,
I just got your message about setConfiguration() and ran into a stumbling
block. Your thoughts would be appreciated.
So, in Blueprints, I'm using a configuration called _blueprints:autokeys which
will maintain the vertex/edge property keys that are being auto-indexed. These
keys, for an index, need to be maintained across opens/closes of Neo4jGraph.
So, when a user updates the autoKeys they are saved to the configuration using
setConfiguration(index, _blueprints:autokeys,
turnHashSetOfStringsIntoASingleParseableString()). Then when the user
Neo4jGraph.shutdown(), everything is out of memory, and the auto keys are
happily in the configuration persisted to disk.
So far, so good.
Next, I load Neo4jGraph again and check to see if my autokeys have been
persisted (in the Blueprints test case). Unfortunately, I note that the code
has to know what the autokeys were to be able to appropriately load the index
without getting an IllegalArgumentException:
Caused by: java.lang.IllegalArgumentException: Supplied index configuration:
{_blueprints:type=AUTOMATIC, provider=lucene, type=exact}
differ from stored config:
{_blueprints:type=AUTOMATIC, provider=lucene,
_blueprints:autokeys=name%%location, type=exact}
for 'vertices'
Doh! ... In other words, it seems that I can't use the configuration in Neo4j
indices to save this information as I need to know this information to load the
index. But to know the information, I have to look at the index's
configuration! :) ...
Thoughts?
Thanks Mattias,
Marko.

Re: [Neo4j] Question about setConfiguration()
Hi Mattias,
I believe I solved my own problem. If I use forNodes(indexName), then
configuration is a wildcard. This seems to be the case, is this true?
However, I seem to be running into a bug where IndexHits.size() 0, but I'm
not getting back what I indexed :( ... I will try and isolate issue and bring
it up in another email.
Thanks,
Marko.

Yup, maybe forNodes(indexName,config) should be called createForNodes
and will only create indexes to get rid of such misunderstandings...
However, I seem to be running into a bug where IndexHits.size() 0, but I'm
not getting back what I indexed :( ... I will try and isolate issue and

Weird, that can be the case if it finds hits, but entities has been
deleted or something.
Thanks,
Marko.

[Neo4j] neoviz + kernel error
Hi all, Tried running the neo-graphviz component and got the following error: org.neo4j.kernel.impl.nioneo.store.IllegalStoreVersionException: Store version [NeoStore v0.9.6]. Please make sure you are not running old Neo4j kernel towards a store that has been created by newer version of Neo4j. at org.neo4j.kernel.impl.nioneo.store.NeoStore.versionFound(NeoStore.java:355)... So I looked at NeoStore.java of the latest kernel source (at /components/kernel/trunk/src/main/java/org/neo4j/kernel/impl/nioneo/store/NeoStore.java) and it seems to only check for v0.9.5, throwing an exception for any other version. Would there be a quick workaround for this? Thanks, Karen Karen Joy Nomorosa Semantic Analyst Project Qhttp://wiki/display/pm/WhatIsProjectQ Tell a little... Get a lot... ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
