如何加快我的網站搜索引擎？

Question

我在搜索引擎中顯示結果時遇到問題。搜索結果需要8秒鐘才能顯示。這是非常漫長的，沒有任何意義。

是否有辦法讓一小部分結果立即顯示（例如，分別顯示第1頁和第2頁），其餘幾秒後？

這是我的代碼：

因爲你的標籤說：PHP我會建議尋找到memcached。你還需要有隻在頁面變化分頁和加載數據，這裏有一個例子：

//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; 

那麼你可以使用在查詢這些限制搶到每頁只有25條記錄。另外我會使用緩存，所以每次更改頁面時都不必執行查詢。
