For issuing search queries, CRS uses the standard Commerce Search /atg/commerce/search/catalog/QueryFormHandler and /atg/commerce/search/catalog/QueryRequest components. The Store.Search.Query module modifies the configuration of QueryRequest to add the /atg/commerce/search/RootCategoryConstraint query constraint. This constraint restricts the search to products under the catalog’s rootNavigationCategory, so products that are not part of the catalog’s navigational hierarchy (such as Gift Wrap) are not returned.
