When you are selecting items from the Product Catalog, Refine Your Search enables you to narrow the list of products to those that match your search filter questions.
Search filters are associated with categories, so that the Refine Your Search options may change when you select different product categories. The options are also found in the product record, which is how the Product list gets refined.
For a product to be displayed on the Catalog page, it must match all of the selected Refine Your Search criteria.
