php - Magento で検索クエリを実装する

Question

SELECT * FROM `table` WHERE
(`name` LIKE '$search' 
OR `address` LIKE '$search'
OR `name` LIKE '$search%'
OR `address` LIKE '$search%'
OR `name` LIKE '%$search%'
OR `address` LIKE '%$search%'
OR `name` like '%$search'
OR `address` like '%$search')
order by 
( (CASE WHEN `name` = '$search' THEN 1 ELSE 0 END)
+ (CASE WHEN `address` = '$search' THEN 1 ELSE 0 END)
+ (CASE WHEN `name` LIKE '$search%' THEN 1 ELSE 0 END)
+ (CASE WHEN `address` LIKE '$search%' THEN 1 ELSE 0 END)
+ (CASE WHEN `name` LIKE '%$search%' THEN 1 ELSE 0 END)
+ (CASE WHEN `address` LIKE '%$search%' THEN 1 ELSE 0 END)
+ (CASE WHEN `name` LIKE '%$search' THEN 1 ELSE 0 END)
+ (CASE WHEN `address` LIKE '%$search' THEN 1 ELSE 0 END))

これらを Magento で検索カスタム Modul で実行したいので、 を配置しようとしました$query->read(".....")が、ページネーションで問題が発生しsetCollection()ます。これまでのところ、次のコードを使用しています。

public function __construct()
{
    parent::__construct();
$search = Mage::app()->getRequest()->getParam("search");
    $collection = Mage::getModel('search/search')->getCollection()
            ->addFieldToFilter('name',array("like"=>"%$search%"));
    $this->setCollection($collection);
}

// next is for pagination
protected function _prepareLayout()
{
    parent::_prepareLayout();
    $pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager');
    $pager->setAvailableLimit(array(20=>20,25=>25,30=>30));
    $pager->**setCollection**($this->getCollection()); // this create probleme whit read() 
    $this->setChild('pager', $pager);
    $this->getCollection()->load();
    return $this;
}

public function getPagerHtml()
{
    return $this->getChildHtml('pager');
}

Magentoの機能が使えるようになればいいのですが。
