title: using entsp in GSA - making no difference to the results
body: <p>I was hoping someone had some experience using the <code>entsp</code> flag in GSA and was able to point out what I am doing wrong.  I've read the documentation but can't figure it out.</p>
  
  <p>The query string I am passing through is:</p>
  
  <pre><code>?as_sitesearch=examplesite.com&amp;callback=angular.callbacks._1&amp;collection=hybrid_site_colection&amp;entsp=a__di_site_biasing&amp;frontend=jsonp&amp;num=10&amp;query=test&amp;start=0
  </code></pre>
  
  <p>I've set up the biasing in the GSA, and when I apply it to the frontend itself, it behaves.  But I was hoping to pass it in dynamically, as I believed you could (we are likely to want to dynamically pass through one of a few biasing, depending on where the user is coming from), it makes no difference.</p>
  
  <p>Am I missing a tag, or can someone see anything else wrong?</p>
