Faceted Search
Faceted search lets shoppers narrow results using structured filters — like size, color, price, or brand — applied on top of a search query or category browse.
Part of Product Discovery
Facets are typically derived directly from catalog attributes, so the filters available depend on how well-structured the underlying product data is. Faceted search and free-text search usually work together: a shopper searches, then narrows with facets, rather than choosing one or the other.
