Commerce Reference Store defines five global facets:
Size -- This facet has
childSKUs.sizeas its faceting property.Color -- This facet has
childSKUs.coloras its faceting property.Features -- This facet has
features.displayNameas its faceting property, wherefeaturesis an array offeatureitems.Price -- This facet gets its value from the
priceproperty created byPriceListPropertyProvider. See Indexing and Querying Price Data for more information about this property.Category -- This facet has
ancestorCategories.$repositoryIdas its faceting property. This Category facet itself is not displayed on the site (it is explicitly hidden by the JSP code that displays the facets), but it is used in determining which other facets to display as a customer navigates the catalog.
In addition, Commerce Reference Store defines one local facet, Wood Finish, that applies only to the ATG Home Store catalog. This facet has childSKUs.woodFinish as its faceting property. This property is present only on the furniture-sku subtype.
