title: Link "equivalent" nodes using Neo4j
body: <p>I confess being new to Cypher. 
  I'm trying to graph Media newspapers in France and the US (Media as a Node) with their PoliticalOrientation (other node). The Relationship [:POLITICAL_ORIENTATION_IS] exists and all is fine.
      MATCH p=(m:Media)-[r:POLITICAL_ORIENTATION_IS]->(o:PoliticalOrientation)
  Now, since those PoliticalOrientations have different names but some are EQUIVALENT between France and the US, like "Left" in France and "Democrats US" in the US, I'd like to create this relationship [:EQUIVALENT] and show the relationships on the graph.
  I'm stuck here, which does not show those [:EQUIVALENT] links:</p>
  
  <pre><code>// custom relations in politics
  CREATE (t:PoliticalOrientation { name:'Democrat US' })-[z:EQUIVALENT]-&gt;(u:PoliticalOrientation { name: 'Left' })
  with t,z,u
  MATCH (m:Media)-[:IS_LISTED_IN_CUSTOM_LISTS]-&gt;(p:CustomLists)
  Match (m)-[:POLITICAL_ORIENTATION_IS]-&gt;(r:PoliticalOrientation)
  MATCH zz=()-[rr:EQUIVALENT]-&gt;()
  WHERE p.name CONTAINS "NEWS" AND NOT r.name = "None"
  RETURN m,p,r,zz,rr
  </code></pre>
  
  <p>Any help is much appreciated. Thanks in advance</p>
