Hi,

You can setup some SKU (product) fields to be searched in the SKU system table. Please see the index settings documentation - at the bottom is described how to set it for SKU objects.

However, if you want to add the product options to the search, you will need to use custom data handler where you will add the product options to the content in OnGetContent event - so they will be indexed as standard content.

Best regards,
