Facets (also called filters) allow users to refine their product searches and navigate the catalogue more efficiently in the front office. They are based on indexed product data and reflect key attributes such as brand, suppliers, attributes, etc.

Facets help create a dynamic, user-friendly browsing experience by displaying only the most relevant filters according to the current product selection.

Facetable Data

The following elements can be used as facets in the front office:

Facet Type	Description	Configurable in Back Office
Supplier	Filters products based on the supplier providing the offer.	❌ No
Product Brand	Filters products by their assigned brand.	❌ No
Product Attributes	Filters by product characteristics such as size, color, or material.	✅ Yes
Offer Custom Fields	Filters based on custom fields defined at the offer level.	✅ Yes
Product tags	Filters products according to their assigned tags.	❌ No
Navigation Categories	Filters products according to their assigned categories in the navigation tree. For more information about how Navigation Categories work as facets, see this page.	❌ No

ℹ️
Non-configurable facets (❌) are managed automatically by the system and are always available when relevant.
Configurable facets (✅) can be activated or deactivated directly in the back office.
Navigate to Attribute and Custom field configuration for detailed configuration instructions.

🚧
Important:
For a facet (such as Brand, Supplier, Category, or any other field) to appear in the front office, it must be linked to at least one online product.
Inactive products, or products not meeting the indexation mode conditions, are excluded from the index — which means their associated facets (e.g., their brand or category) will not be displayed in the filters.

Facet Combination Logic

When users select several filters in the front office, the system combines them using two different types of logic, depending on whether the values belong to the same facet or to different facets.

Case	Logic Applied	Example	Result
Multiple values within the same facet	OR	Facet: Color → selected: Red and Blue	Returns all products that are Red, Blue, or both.
Multiple different facets	AND	Facets: Color = Blue and Size = Medium	Returns products that are Blue and Medium.

This ensures a flexible and intuitive filtering experience:

Users can broaden results within a single facet (OR).
They can narrow results by combining different facets (AND).

Best Practices

Enable facets only for relevant attributes to keep navigation fast and clear.
Avoid using too many facets on a single page, as this can impact performance and usability.
Regularly review your facets to ensure they match current catalogue data and business needs.
Remember to reindex the catalogue after updating facet configurations to apply the changes.
