Hi Wilfried,
Thanks for the reply. FOR..OUTBOUND is extremely slow when we had to find
neighbors with higher depths. How about an array? Is it possible to use it
as follows..
FOR e IN GRAPH_NEIGHBORS("
........> +"'routeplanner', {}, {edgeExamples : [{distance: 600}, {distance:
700}, {route[0] : 1}]}) RETURN e"
........> ).toArray();
