title: JQgrid multiple search not working
body: <p>I have a JQGrid in my page where I gave search options as below. But I cant get any multiple search active. The search pop up only has single search. The "ADD", "OR" drop down and the 'plus' icon are not coming. FYI I am using IBM Domino. Why is it so?</p>
  
  <p>Code : </p>
  
  <pre><code>$("#...").jqGrid ({
    ...
    ...
    search : {
      caption : 'Filter',
      multipleSearch : true
    }
  });
  </code></pre>
