I'm a total n00b at Magento, and I need to hide sold products from the inner (i.e. Magento's built-in) search engine. BUT I don't want to hide them regarding Google searches.
This means: the url for the product should still be indexable by Google, but should not be returned by the Magento inner / in-site search.
Question: Is there a way to filter the Magento search engine, so the already-sold products are not returned?
