java - How to merge two different paths such that no edge is common in between them? -


i using neo4j graph database , java coding. getting 2 unique paths as-

(2)--[knows,4]-->(4)--[knows,6]-->(5)--[knows,9]-->(6)  (6)<--[knows,9]--(5)--[knows,8]-->(8)--[knows,11]-->(7)--[knows,12]-->(9) 

but when merging them follows

(2)--[knows,4]-->(4)--[knows,6]-->(5)--[knows,9]-->(6)<--[knows,9]--(5)-- [knows,8]-->(8)--[knows,11]-->(7)--[knows,12]-->(9) 

as can see edge (6)--(5) repeating.

plz tell how this?
