我想在 Magento 中为搜索自定义 Modul 执行这些操作并尝试放置$query->read(".....")，但这会导致setCollection()分页出现问题。到目前为止，我使用以下代码：

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');
}

我想要是否可以使用 Magento 功能。
