AbleCommerce Shopping Cart Software

Does anyone know exactly which fields in the database the built-in basic and advanced product search features search against? A client has asked me for this information and I can't seem to find the answer in the forums or by looking at the code or database. It's a simple question and probably been answered before and I'm just missing it.

Following information is taking part in product related searches
ac_Products.Name,ac_Products.Summary,ac_Products.Description,ac_Products.ExtendedDescription,ac_Products.SearchKeywords,ac_Products.Sku,
ac_Products.ModelNumber,ac_Products.Price,ac_Products.ManufacturerId, parent categories information.
