从Magento中的自定义块调用CatalogSearch的正确方法是什么？

Question

我正在编写一个控制器,旨在将Magento的目录搜索功能暴露给API调用.使用具有默认REST api的过滤器不会返回与Magento站点上可用的搜索功能相同的质量结果.

我现在已经挖掘了几天了,我在Stack Overflow和Magento讨论板上看到的各种方法似乎都没有用,我是否缺少一个步骤？

这两种方法都返回null,我似乎无法弄清楚原因:

 $query = Mage::helper('catalogSearch')->getQuery();

 $searcher = Mage::getSingleton('catalogsearch/advanced')->addFilters(
             array('name'=> $query->getQueryText(), 
             'description' => $query->getQueryText()));



 $obj = new stdClass();
 $obj->query = $query->getQueryText();
 $obj->results = $searcher->getProductCollection(); //nothing returned

从这个SO问题修改的方法似乎也不起作用:

 $query = Mage::helper('catalogSearch')->getQuery();

 $obj = new stdClass();
 $obj->query = $query->getQueryText();

 if ($query->getQueryText()) {
      if (Mage::helper('catalogSearch')->isMinQueryLength()) {
           $query->setId(0)->setIsActive(1)->setIsProcessed(1);
      } else { 
           if ($query->getId()) { 
                $query->setPopularity($query->getPopularity()+1);
           } else { 
                $query->setPopularity(1);   
           }
           $query->prepare();
       }
       $obj->results = $query->getProductCollection(); //null
}

成功调用Magento的目录搜索模块并获取结果集合后,我缺少哪些步骤？

Magento的搜索模型有点复杂,因为它们构建了一种机制来保存查询和缓存和统计结果.因此,您需要准备查询对象,然后准备结果,然后您可以将产品集合与搜索结果表一起加入.以下是如何在代码中执行此操作:

$searchText = 'ipad';
$query = Mage::getModel('catalogsearch/query')->setQueryText($searchText)->prepare();
$fulltextResource = Mage::getResourceModel('catalogsearch/fulltext')->prepareResult(
        Mage::getModel('catalogsearch/fulltext'), 
        $searchText, 
        $query
        );

$collection = Mage::getResourceModel('catalog/product_collection');
$collection->getSelect()->joinInner(
            array('search_result' => $collection->getTable('catalogsearch/result')),
            $collection->getConnection()->quoteInto(
                'search_result.product_id=e.entity_id AND search_result.query_id=?',
                $query->getId()
            ),
            array('relevance' => 'relevance')
        );

$ collection是一个已过滤的目录产品集合,您可以根据需要执行任何其他操作:

$collection->setStore(Mage::app()->getStore());
$collection->addMinimalPrice();
$collection->addFinalPrice();
$collection->addTaxPercents();
$collection->addStoreFilter();
$collection->addUrlRewrite();

Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
