HierarchicalFaceting for Ecommerce Categories

[Nea]

Hi Everybody,

I’m using Solr 4.5.1 and I need to achieve a HierarchicalFaceting for leveled 
categories. Someone can explain me how schema.xml and query should be?


My category path is;

Cameras > Camcorders                                                    [  5 
items]
Cameras > Digital Cameras
Cameras > Digital Cameras > Digital SLR                 [15 items]
Cameras > Digital Cameras > Mirrorless Cameras          [  4 items]


And i want to facet as;

first query:
        cameras (24)

second level query
        camorders (5)
        digital cameras (19)

third level facet query for digital cameras
        digital slr (15)
        mirrorless (4)
