title: Globally exclude cloned items from index?
body: <p>I am looking for an elegant way to exclude cloned items from my web index. I am having items appear as duplicates in my search results. I'd prefer it if only the original items appear and no clones at all.</p>
  
  <p>Some possible solutions that come to mind are to:</p>
  
  <ol>
  <li><p><strong>Create a <code>Global Item Boosting Rule</code> to drastically lower the boost value if the item's <code>_Source</code> field is not empty.</strong> This is not preferred as it only lowers the score and does not remove the clones from the search results.</p></li>
  <li><p><strong>Exclude the cloned items in every query that I perform using an extended Where clause.</strong> This is also not preferred as it means that I need to remember to include this clause on all queries. Furthermore, the cloned items still remain in the index.</p></li>
  </ol>
