(As I answered in another thread) This is a bug in the LuceneIndexBatchInserterIndexProvider class where it doesn't automatically fill in the "provider" parameter. It has been fixed now, so until M03 send that in yourself... just like the tests do.
I'm not sure this is connected to the python problems, since the python bindings hasn't been updated to use the new index API, and is even batchinsertion possible in neo4j.py? I think it's not. 2010/10/26 Peter Neubauer <peter.neuba...@neotechnology.com> > Hi all, > there are two cases (from python and Paddys code below) where a > created index is not found.
