I need my quick search to search by SKU. I know that's the way Magento works by default but unfortunately that's only for simple products (I think).
In my case, I have a store that uses simple products set to "not visible individually", and then I have grouped products that associate those simple products. Only the simple products have the SKU attribute but they're only shown when you open the grouped product.
What I need then, is to have it search inside those grouped products for the simple products with the SKU entered in the quick search field, and then display the grouped products that have a match.
Is there anything that does this? Seems to me it should be baseline in Magento.
Edit: Magento 1.4.2
