title: Finding all indirectly connected nodes with specific relationship Gremlin
body: <p>Suppose I have the numerical ID of a Node in Gremlin.. utilized with</p>
  
  <pre><code>g.V(n_id)
  </code></pre>
  
  <p>Say this Node is a topic. </p>
  
  <p>Each topic can have a question with relationship <code>threadOf</code>.</p>
  
  <p>Each question can have an answer or comment with relationship <code>threadOf</code></p>
  
  <p>If I get a numerical ID as an input I'd like a gremlin query which returns all the questions related to this topic and all the answers or comments related to those questions</p>
  
  <p>All relationships are <code>threadOf</code></p>
  
  <p>Is this possible with Gremlin?</p>
