title: jqgrid - filter/search always gives me only "contains" operator for a option
body: <p>I am using jQgrid - and it is great!</p>
  
  <p>I have one problem.
  (Oleg are you still around?)
  In the search/filter form (were you can choose the coulmn you want to filter and the operation you want do to), the only things that comes up is the "contain" operator.</p>
  
  <p>My colModel looks like this:</p>
  
  <pre><code>var columnModel = [{ name: 'ID', index: 'ID', sortable: true, searchoptions: { sopt: ['eq', 'cn','bw']}},
  { name: 'FirstName', index: 'FirstName', sortable: true},
  { name: 'LastName', index: 'LastName', sortable: true }
  ];
  </code></pre>
  
  <p>But it only gives me the contains operator.</p>
  
  <p>The full grid is like this:</p>
  
  <pre><code>myGrid.jqGrid({
      url: './ViewNQueryData.asmx/ViewNQueryData',
      datatype: 'json',
      mtype: 'POST',
      postData: {userID:currentUserId, sphereID:currentSphereId},
      ajaxGridOptions: { contentType: 'application/json; charset=utf-8' },
      serializeGridData: function (postData)
      {
          if (postData.filters === undefined) postData.filters = null;
          return JSON.stringify(postData);
      },
      jsonReader: {
          root: function (obj) { return obj.d.rows; },
          page: function (obj) { return obj.d.page; },
          total: function (obj) { return obj.d.total; },
          records: function (obj) { return obj.d.records; }
      },
      colModel: columnModel,
      colNames: columnNames,
      rowNum: 10,
      rowList: [10, 20, 300],
      sortable: true,
      pager: "#ViewNQueryPager",
      viewrecords: true,
      gridview: true,
      height: 250,
      shrinkToFit: true, //If using frozen coulmns change to false.
  
      gridComplete: function ()
      {
          $('#totalRecordsFound').html(myGrid.jqGrid('getGridParam', 'records') + " Customers");
      },
      loadError: function ()
      {
          alert("Error fetching data");
      }
  }).jqGrid('navGrid', '#ViewNQueryPager',
                  { edit: false, add: false, del: false, search: true, view: true }, //option
                  {}, // use default settings for edit
                  {}, // use default settings for add
                  {}, // delete instead that del:false we need this
                  {multipleSearch: true, multipleGroup: true, showQuery: true, onSearch: function (response) { showQueryDetails(); } },
                  { height: 250, jqModal: false, closeOnEscape: true} // view options
                  );
  </code></pre>
  
  <p>Can any one help me with this??? </p>
