Hi Peter,

thanks for the reply. I can't say that it's not ok for me, can I? :)

In my previous mail I mentioned errors such as "Node[xyz] has been 
deleted in this TX". Turns out I had forgotten to clean all indices 
(because there does not seem to be a way to find out which indices exist 
currently). Anyway, the errors are gone so I'm fine for now.

Just for reference, what I'm doing is:

   - graph.getAllNodes()
   - iterate over all the nodes
   - for each node delete all its relationships
   - delete the node
   - after deleting all nodes delete the indices

Guess I didn't have to tell you that :)

Still, thanks for picking up that item for your to-do.

Thanks and best regards,
Georg
