To enable users to filter by an attribute on the storefront, a Search Refinement Definition must be explicitly created for that attribute within the Business Manager. This definition controls how the attribute appears and behaves as a filter, including its display name, sorting order, and value bucketing. While the attribute must be marked as "Searchable" as a prerequisite, that step alone does not create the user-facing filter. The creation of the refinement definition is the direct and necessary action that makes the attribute available for filtering in the storefront's refinement bar.

"Search Refinements": "To use a product or content attribute for search refinement

you must first configure the attribute to be searchable. You then create refinement definitions for product or content attributes in Business Manager." This source confirms that creating the refinement definition (Option A) is the distinct step that enables the filter

subsequent to making the attribute searchable (Option B). The definition is what achieves the filtering capability. (Reference path: Salesforce Help > B2C Commerce > Merchant Tools > Search and Navigation > Search Refinements).

"Configure Search Refinements": "You can configure which attributes appear as search refinements on the storefront... Go to Merchant Tools > Search > Search Refinement Definitions and select the attribute." This documentation specifies the exact action and location in Business Manager for creating the filter

directly supporting Option A as the correct procedure. (Reference path: Salesforce Help > B2C Commerce > Merchant Tools > Search and Navigation > Configure Search Refinements).

3. Salesforce B2C Commerce Infocenter

"Attribute Definitions": This documentation describes the "Searchable" flag as a property of an attribute definition itself. It states

"Select if you want the attribute to be searchable." This confirms that being "Searchable" is a general property

distinct from the specific configuration as a filter/refinement. (Reference path: Salesforce Help > B2C Commerce > Merchant Tools > Products and Catalogs > Product Attributes > Attribute Definitions).
