     <p>These filters are run after a previous part of a selector has already returned results. <code>setFilters</code> are found from matching <code>jQuery.expr.match.POS</code>. When applicable, <code>argument</code> is expected to be an integer. The <code>not</code> argument is a boolean indicating whether the result should be inverted (as in <code>div:not(:first)</code>).</p>
