Magento系统：脱销产品（stock_status=0）不显示在搜索结果里面！
修改：app/code/core/Mage/CatalogSearch/Model/Mysql4/Fulltext/Collection.php 第59行,在中间添加一个AND条件，代码如下：
AND search_result.product_id in(SELECT product_id FROM cataloginventory_stock_status WHERE stock_status!=0)
也就是把：
'search_result.product_id=e.entity_id AND search_result.query_id=?',
替换为：
'search_result.product_id=e.entity_id AND search_result.product_id in(SELECT product_id FROM cataloginventory_stock_status WHERE stock_status!=0) AND search_result.query_id=?',
