Steve Molloy updated SOLR-4212:
-------------------------------
    Description: 
Facet pivot provide hierarchical support for computing data used to populate a 
treemap or similar visualization. TreeMaps usually offer users extra 
information by applying an overlay color on top of the existing square sizes 
based on hierarchical counts. This second count is based on user choices, 
representing, usually with gradient, the proportion of the square that fits the 
user's choices.

The proposition is to use local parameters to specify facet query to apply for 
pivot which matches a tag set on facet query.

representing, usually with gradient, the proportion of the square that fits the 
user's choices.

The proposition is to add a facet.pivot.q parameter that would allow to specify 
one or more queries (per field) that would be intersected with DocSet used to 
calculate pivot count, stored in separate qcounts list, each entry keyed by the 
query.
