This works fine now, but I am still looking for method of FAST access as
claimed on Stackoverflow thread
<http://stackoverflow.com/questions/10970556/orientdb-graphdatabase-osqlsynchquery-for-rid-to-get-graph-getvertexrid?rq=1>
OIndex<?> nameIdx = graph.getRawGraph().getMetadata().getIndexManager().
getIndex("idxtest2");
Object luke = (Object)nameIdx.get( "06615119" );
System.out.println(luke);
