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.
