Facet filters & dynamic faceting

Feature	Description
Facet filters on any product attribute	Faceted filters can be built using any product attribute (date, number or text). Brand, category and price are default. Allow users to select and deselect facets. Applying a facet will narrow the search results and new facet values will be re-calculated based on the filtered results. All faceting options with a value >0 (i.e. the count of products that contain that filterable attribute) will be returned.
Dynamic faceted filters	The engine can decide what facets are relevant for the current search result and strip away any irrelevant facets. This is particulary relevant for stores with many facets and a lot of broad searches.
