如何为bootgrid设置搜索

<table id="grid-data" class="table table-condensed table-hover table-striped">
  <thead>
    <tr>
      <th data-column-id="id" data-type="numeric">ID</th>
      <th data-column-id="name">Name</th>
      <th data-column-id="email">Email</th>

</table>

$(document).ready(function(){
  $("#grid-data").bootgrid({
    ajax: true,
    url: "data.json", // 替换为您的数据源URL
    search: true,
    searchSettings: {
      delay: 100,
      characters: 3
    }
  });
});
