如何加快我的搜索引擎网站？

我在搜索引擎中显示结果时遇到问题。搜索结果需要8秒才能显示。它很长，没有意义。

有没有办法立即显示一小部分结果（例如，分别显示第1页和第2页），其余几秒后显示？

这是我的代码：

public function index($destination_main_id=null,$accommod_main_id=null,$search_period_code=null,$total_person=null,$pageNum=null, $order=null, $range_days=null){

if(!empty($_POST['filter'])){
$this->set('ajax_load',1);
}else{
$this->set('ajax_load',0);
}

//inicijacija varijabli
if(!empty($_POST['radio1'])){
$this->request->data['SearchEngine']['accommod_main_id']=$_POST['radio1'];
}

if($order==''){
$order='asc';
}

$range_days=0;
}

if(!$search_period_code){
$search_period=$this->Calendar->getDatesBetweenDates($this->request->data['SearchEngine']['arrival'], $this->request->data['SearchEngine']['departure']);
$search_period_code = base64_encode(serialize($search_period));
}else{
$search_period = @unserialize(base64_decode($search_period_code));
}
$count_search_period=count($search_period);

由于您的标记显示 php ，我建议您查看memcached。此外，您还需要在页面更改时使用分页和加载数据，这是一个示例：

 //user clicked page number, 1,2,3 etc...
 $currentPage = isset($_POST['page']) ? (int)$_POST['page'] : 1; 

 // get 25 rows per page
 $startLimit  = ($currentPage-1) * 25; 
 $endLimit    = $startLimit + 25;

然后您可以在查询中使用这些限制，每页只能抓取25条记录。此外，我会使用缓存，所以每次更改页面时都不必执行查询。
