如何在搜索中存储参数，以便在显示结果时可以检索它？ （Magento的）

I need to search for some products' custom options (set in Manage Products|Edit Product|Custom Options), the only way I've found is manually filtering the results returned by Magento's search function. The question is: How do I store the info I need, so I can remove products not matching my criteria --once Magento returns its results?

Thanks!

You can use the Mage::registry approach which stores data per request. To store it:

if(!Mage::registry('custom_search_critera')){  //check not already set
   Mage::register('custom_search_critera', $values);
}

To retrieve from another object or function:

$values = Mage::registry('custom_search_critera');

In the session of course :) This is the first thing that comes to me and I guess it is the best approach.

For data that you need to persist, use Magento sessions:

Mage::getSingleton('core/session')->setXXX( 'SomeData' );
Mage::getSingleton('core/session')->getXXX();

(where XXX is some identifier, eg setSomeVeryImportantInfo)

I've also found 'customer/session' and 'admin/session'.
