Environments that have Merchandising and Search installed can use a feature called facets. A facet is a way of constraining searches to return groupings of products based on a property value. When you implement facets in site pages, you see groupings that appear as a range of selections named for property values or letters in the alphabet that represent them. By clicking an A-C selection, you can view products, for example, that have a manufacturer name that begins with those letters.

Depending on how you define your facets, they may be available on individual sites only or across multiple sites. For details on creating facets for a multisite application, see the ATG Merchandising Guide for Business Users. For information on designing pages that use facets to refine the lists of products displayed to users, see the ATG Search Query Guide.
