title: Sequelize: Where is an example of using bulkDelete with criteria?
body: <p>I'm trying to write a seed file's <code>down</code> and I'd like to <code>bulkDelete</code> the data I created in my <code>up</code>.  But I can't find any documentation on how to do this.  The official docs don't give an example: <a href="http://docs.sequelizejs.com/class/lib/query-interface.js~QueryInterface.html#instance-method-bulkDelete" rel="noreferrer">http://docs.sequelizejs.com/class/lib/query-interface.js~QueryInterface.html#instance-method-bulkDelete</a></p>
  
  <p>Can someone show me how to <code>bulkDelete</code> all rows in table <code>Foo</code> where <code>name</code> equals <code>x</code> or name equals <code>y</code>?  </p>
  
  <pre><code>  down: (queryInterface, Sequelize) =&gt; {
      return queryInterface.bulkDelete('Foo', [what do I put here?], {});
    }
  </code></pre>
