Hi,
The scenario is the following :
I use Gremlin over Rexster,
Through gremlin I created 2 automatic indexes that were not presents :
edges and vertices
When I add some vertices a properties I can search them through the
index
When I stop the rexster server, start the neo4j-1.2 one and add
vertices through neography (rails gem for connecting to neo4j), this
works
Then I stop the neo4j server, restart rexster and reconnect through
gremlin.
When I want to do a : g.idx(T.v)[[project:61]] I got this exception :
org.apache.lucene.index.CorruptIndexException: Incompatible format
version: 2 expected 1 or lower
So far on the neo4j side I have these jars :
neo4j-lucene-index-0.2-1.2.jar
org.apache.servicemix.bundles.jline-0.9.94_1.jar
org.apache.servicemix.bundles.lucene-3.0.1_2.jar
On the gremlin side :
neo4j-lucene-index-0.2-1.2.M05.jar
org.apache.servicemix.bundles.jline-0.9.94_1.jar
org.apache.servicemix.bundles.lucene-3.0.1_2.jar
What is wrong ?
Best Regards,
Manfred

Hi Manfred,
This looks to be a Lucene version issue, not a Neo4j issue. Have you
run your application with a later (or earlier) version of lucene on
the classpath prior to upgrading to neo4j 1.2, or there's maybe
another lucene version on your classpath after the upgrade?
The lucene version which neo4j-lucene-index depends on hasn't changed
since june 2010.

Hi Manfred,
As a side....and potentially causing the problem:
Rexster 0.1 currently only supports Neo4j 1.2M05 and Gremlin 0.6. (see the pom.xml)
There hasn't been a new release of Rexster that bumps all of this up a notch.
I will make it a priority to get a new version of Rexster pushed.
Thanks,
Marko.

Hi Alex, Hi Mattias,
Yes, that can be a rexster version problem, and yes the fact that it
is Gremlin 0.6 does not allow to use the groovy gremlin language.
Also to confirme this is the problem, what I can do is to restart for
a fresh install of neo4j, recreate a graph , put the data in it and
see what's happening
Best Regards,
Manfred
