Ah, it's a bug allright... only when using the BatchInserterIndex. The problem goes away if you add "provider":"lucene" to the configuration map, like:
persons= indexProvider.nodeIndex("persons", MapUtil.stringMap("type","exact", "provider", "lucene")); It will be fixed in M03, where the LuceneBatchInserterIndexProvider fills that in for you. 2010/10/26 Peter Neubauer <peter.neuba...@neotechnology.com> > Paddy, > just tested it, and it seems it only occurs when running standalone, > see the other mail.
