magento 开启solr 产品列表属性筛选无效 ，solr layered navigation 不起作用。比如价格属性筛选等
一：debug了一段时间，发现solr返回的$this->_searchedEntityIds = &$ids; 被执行两次，也就double sql,
结果是GA造成个collection 复用，产品list页面调用getLoadedProductCollection
$_productCollection = Mage::getBlockSingleton(“catalog/product_list”)->getLoadedProductCollection();
$_productCollection_clone = clone $_productCollection;
二：double sql问题解决还是筛选无效，发现是layout layered里面为调用serch 类型的模板
