Neo4j Cypher query : Club users likes with friends like -


I have a neo4j graph that looks like this: 

  (user) - Like- & Gt; (Actor) | ^ | | Like friends | Wei | (User2) -----------   
 Who says, user2 and user's user actor and friend (user 2) liked actor also likes .  
 Now, given actor, when I try to drag the friends of all the users who prefer the actor, then I do something like this:  
  Start user = Node (*) match (user) - [: friends] - (friend) - [liked_rela: likes] - (actor) where user.UID = 123 and actor.id = 234 returns different friends, like_rela;   
 The above questions have returned friends of all my users, who prefer an actor. It does not return the relationship between the user and the actor. Is there a way that I can club it in the same question?  
 I am using Neo4j 1.9  
 thanks   
 
 < P> This can happen after you:  
  MATCH (user {id: 123}) - [: friends] - (friend) - [f_like_rel: likes] - & gt; (Actor (id: 234)) Alternative match (user) - [u_rel] - (actor) returns different friend, u_rel, f_like_rel;   
 Note:  
     
  1.  The above  (user {id: 123}) - [: friends] - (friend)  Pattern < Code> (friend) - [f_like_rel: likes] - & gt; (Actor {1}), which can go any way in  friends  relationship.  
  2.  ID: 234})  Pattern is directional, as I believe you do not want to capture any actor who likes your friend (without any realization) the resulting).  
  3.   u_rel  may be of type  friends  or  preference ; Or it may be  NULL  if the user has no relation with the actor I have left this pattern non-directional, but you want to make it directional.
