Faceted navigation is an alternative entry point to search. It offers a convenient alternative to typing complex search expressions by hand. Facets can help you find what you’re looking for, while ensuring that you don’t get zero results. As a developer, facets let you expose the most useful search criteria for navigating your search index.
In contrast to hierarchical navigation based on only one attribute, faceted navigation offers users the ability to navigate to desired items based on several attributes. In addition, users can select any available attribute to start their navigation. Another important benefit is that an empty result set is not possible with faceted navigation.
