Hi, I'm trying to configure neo4j to run on an amazon ec2 instance. This is my first time using ec2, I'd like to deploy a neo4j web app war file to Jetty. So far I have been reading the following tutorials on how to setup Jetty on ec2. If anyone has any previous experience deploying a neo4j app to

Balazs, Mattias is writing this component, not sure how stable it is right now, but as I perceived it the API is starting to settle ... Would be great to get some more indexes tried out, feel free to experiment with Sphinx, might be a good alternative to Lucene? Cheers, /peter neubauer COO and

Thanks to Anders and Peter for getting the build up and running :-) The current OSM imports do not yet expose themselves properly as indexed layers, but we are very close to closing that gap. I'm nearly finished a refactoring that respects the fact that one OSM dataset actually represents multiple

Hi Craig/Davide, seems we are running with real data now and can see Esri Shapefiles and OSM XML data being imported and grouped into layers. Well done guys. Now probably there should be more tests demonstrating routing etc as part of the documentation, but it's exiting to see this emerge! http://

That's great, works as expected. :-) Now, it seems you changed a lot of the indexing APIs. Should I use these new ones (and the neo4j sources from the SVN trunk), as these will be used in future versions, or these are still experimental? I ask this because in parallel we also investigate the po

Hi, I'm new to neo4j and have read quite a lot of documentation and source code and it seems that one can only do queries on a single Node property (a single indexed value mapped to a key) using : IndexHits getNodes( String key, Object value ) This seems to be true for LuceneFulltextIndex
