title: Titan GraphDB query within a set
body: <p>I have edges that has a property called <code>type</code> that stores the different type of relationships between two vertices. The <code>type</code> property is a set. I was wondering how can I query to get the edges that contain that type?</p>
  
  <p><strong>For example:</strong></p>
  
  <p>Types = [A, B, C] <br>
  Edge1.type = [A, B] <br>
  Edge2.type = [B, C] <br>
  Edge3.type = [A, C] <br></p>
  
  <p>If I query for edges with type A, I would get Edge1 and Edge3.</p>
