Sulabh, if you want to get the property relationships, I would either get these during the iteration of the nodes you get back (thus in some way duplicating the Evaluator in the result iteration, but you could possibly refactor that into one method), or during the traversal build up a resultset that contains both the nodes and the relationship(properties) you need. That could possibly lead to memory problems if the results are very big.
WDYT?
