对二个页面搜索怎么写?

HTML code
<form id="form1"name="form1"method="post"action=""><select id="searchselect"><option value="aaa/search.php">aaa</option><option value="bbb/search.php">bbb</option></select>                        <input id="keyword_s" type="text" name="keyword" /><input type="submit" name="submit" value="搜索" /></form><script type="text/javascript"><!--function cksearch(){    if (document.getElementById("keyword_s").value=='')    {        alert('关键字不能为空!');        return false;    }}//--></script>


我想当我在下拉框选择aaa时,点搜索是对aaa/search.php文件进行搜索,

当我在下拉框选择bbb时,点搜索是对bbb/search.php文件进行搜索,我的文件应该怎么写?
