There are tests which shows that a custom analyzer is used when adding to an
index... and the analyzer config parameter can override the
type:fulltext parameter (in the SNAPSHOT version at least). So,
code-wise, look at IndexType which instantiates a custom analyzer and use it
for that index. Both

Hi Mattias,
Even if I pass nulls, I will still have to build an index on some key
(property). I do not want to do that because it adds the property
index overhead for something that I am not actually using.
I think it's definately worth

I already used the regular index to lookup for existing relationships as
workaround. it's definitely faster then looping specially when database is
growing.
it will be really useful to have an index for relationships.

This looks to be a lucene version issue. You probably filled the index with
a recent neo4j milestone, am I right? Whereas the webadmin depends on neo4j
1.1, where 1.1 has an older dependency on lucene... hence the version
mismatch (lucene data isn't backwards compatible v.3 - v.2) it seems.
Francois,
I am right now updating the webadmin dependencies to be more recent.
We moved the code to https://svn.neo4j.org/components/webadmin/trunk/
in order to be able to do a proper release for it next week, which
will include the updated dependencies. Meanwhile, let me just finish
the updating
many thx.

Francois,
now the updated webadmin component as of rev 6460 should build, pull
down a fresh kernel/rest etc, and run against your store that you
create with 1.2.M02.
Could you please build it and verify? The snapshot dependencies are in
the m2.neo4j.org Maven repo, you will need to point it out
Thx Peter.

You can use the prebuilt versions as well:
http://neo4j.org/get?file=neo4j-webadmin-standalone-0.0.1-SNAPSHOT.tar.gz
http://neo4j.org/get?file=neo4j-webadmin-standalone-0.0.1-SNAPSHOT.zip
The readme file etc. is missing in this build, but otherwise it works.

Since I don't have Administrator privileges on my PC at work, if I wanted
to try the Windows version of this package I would have to have a way to

Thanks for the input everyone! It seems an Ubuntu/Debian installer
would be the best thing to start with, apart from a simple .zip

Yeah, true,
I think there will be more to come, but if we want to keep the 3 weeks
release cycle with some quality, we need to start somewhere :)

By the way, does the underlying code for index.get(kay, value, start,
end) iterate over all the relationships of start and checks if one is
connected to end, or it does perform a direct look up to get the edges
between (start, end)?
No looping, just a direct lookup. Maybe RelationshipIndex
Haha,
that was a Freudian misspelling - we are aiming for 2, not 3 weeks cycles :)

Of course you can use alien to install a debian package on Red Hat and
other linux packages.

I think if you get one to work, the other's will follow fairly quickly.
Personally, I think a .deb package should not be the first step. Let's get

Hi everyone,
I'm running Neo4j on both Ubuntu and Windows 7 boxes. I have a dataset with
200 million edges and 10 million nodes with a median branching factor of
about 50 outgoing, directed edges/node. I'm trying to run the BFS search on
the data but am fairing unsuccessful in being able to do so
Milan,
this content is stale and should be removed. The current Roo addon is
not totally done, but parts of it are already usable, see
http://wiki.neo4j.org/content/Neo4j_and_SpringOne and
http://github.com/neo4j-examples/spring-datastore-graph-imdb for some
example code and projects.
Feel free
David,
could you post your neo4j.properties configuration, so we can see how
that is configured? Also, what is the size of your store files?
I guess you are right, there is a lot of reading/writing going on. Do
you see any differences in Windows vs. Linux?
Cheers,

GTalk:
Do you actually want to do a BFS (assuming that means breath first search)
and get all those paths back, or are you just testing performance? Also if
it's the first run for that GraphDatabaseService instance you're basically
testing your I/O performance on your hard drive since everything will

Mattias,
So Direction.BOTH means to traverse from both sides, not that the
relationships are directed, correct? I completely misinterpreted that and
used Direction.OUTGOING to indicate that my relationships were not
bidirectional. Thank you!
