  Hierarchical Facets
===================

 A special variant of the faceted search are hierarchical facets. These allow to represent trees, e.g. categories, in the index. This way documents can be "added" to multiple properties representing a hierarchy. When selecting a higher level hierarchical facet all documents matching the facet and its children are selected.

For example, selecting "shoes" as a facet would list running shoes, sneakers, and hiking shoes.
