title: Google Analytics - Is head match of goal URL any substring of the actual URL
body: <p>I have 2 urls to be tracked under a single goal :</p>
  
  <pre><code>/vpv/purchase_item
  /vpv/purchase_coupon
  </code></pre>
  
  <p>So, I have setup a head match as /vpv/purchase.</p>
  
  <p>Is this correct, as <strong>/vpv/purchase</strong> is a substring of both the urls i need to track ?
  Or does head match considers the complete URL except the query string ?</p>
