我已经实现了一个显示所有记录的搜索功能，当我搜索它时会用分页过滤所有记录。分页搜索结果
虽然有一个问题：每次搜索一条记录时，它会显示所有页面，但是当我单击第二页时，它会显示数据库中的所有记录 - 而不是我想要过滤的内容。
这里是我的代码：
<form id="form1" name="form1" method="get" action="">
<br/>
<div>
<font color ="white" face ="Arial" size ="5" style="padding: 5px; text-align: center;">Search for an Applicant Record</font><br/><br/>
<table border=0 cellSpacing=2 cellPadding=2 align ="left" >
<tr>
