title: Search All Columns in KendoUI Grid
body: <p>I am trying to create a search box for a kendoUI grid. I have been able to get a start on doing a search based on one field however I would like the value in my search box to search all columns in the grid.</p>
  
  <pre><code>function() {
              grid.data("kendoGrid").dataSource.filter({
                  field: "ProductName",
                  operator: "contains",
                  value: $('#category').val()
              });
  
          }
  </code></pre>
