I'd probably go for that as well.
It's harder to go with a gut feeling for the case where you have many
categories... it may be better to go with relationships then, because you
gain the traversal aspect of it which you don't really get if you go with
properties.

Hi,
Good work on 1.1 release.
I am trying to make 1.1 work with neo4j.py.
However I got some error.
Tried CPython+Jpype and Jython, both failed.
I'm using Jython 2.5.1 on ubuntu 10.04 x86_64 with openjdk-6-jre.
The code I tested:
neodir = '/opt/neo4j-apoc-1.1/lib'
db =

executing that code, I get the following output:

Alberto,
Hope your testing is coming along well. Feel free to post your progress to

But then you need to store the result. You can store these metrics as
relationships in neo4j,
Hi,
I have a problem with the LuceneIndexService. When I create an indexed
graph base and I commit it to disk, next time I want to use it, I get
a NoSuchMethodError for LuceneIndexService.getSingleNode:

Hi Jeff,
If I'm not mistaken, Neo4j loads all properties for a node or relationship
when you invoke any operation that touches a property. As for the
performance of traversals, it is highly dependent on how deep you traverse,
and what you do during the traversal, so ymmv.
Using a traverser is
Hi Tim,
It is not possible to mark a transaction as read-only. As Martin said, you
don't need a transaction to perform read operations. If you have a
transaction but don't do any writes, then it won't commit anything. So as
long as you don't do any writes, you shouldn't experience any delays when
Max,
this sounds like a version clash on Lucene. Can you check what
version(s) of Lucene (and Neo4j-Index) you are running in the two
scenarios?

I tracked down the error. There was still a left-over imported Lucene
3.0.2 in the library, which does not have the method Hits
IndexSearcher.search(Query).
Thanks for the hint Peter!
Best,

Max,
since you are using neo4j-index, you should not be importing Lucene
again, since it already is a dependency of the index components (and I
think the version is higher there).
So, upgrading to 1.1 and removing the Lucene dependency should fix it:

I am doing a bounding box query on the geo data that I have imported into the
