Within the Digital Market platform there are two search fields. They allow you to search different for different things.
"Search and Order Products" located on the dashboard screen, searches across all of the Digital Market products (across each brand/ catalog)
For example if you search hat here, you will see hats in all brands on the platform.
"Search Catalogs" allows you to find a specific catalog by name so that the buyer can quickly find the brand they want to shop.
Within View Catalog or Build Order screens, the "Keyword Search" will allow you to search over product name, product number, color name, color code, UPC/SKU. Depending on what text you enter here, the system will return multiple matches (ex. 20 products that all match the color name searched) or an exact match (ex. 1 product with the exact UPC/SKU).
