Shalin Shekhar Mangar updated SOLR-4212:
----------------------------------------
Attachment: SOLR-6353-6686-4212.patch
# Further refactored and shared code between FacetComponent and
PivotFacetField/PivotFacetHelper for range faceting
# Removed dependency on mahout-collections. I found that using it actually made
the merging logic more complex involving reordering the facet results in the
output
# Introduced a RangeFacetAccumulator which is actually quite simple and
encapsulates all logic for tracking and merging range facet results from
different shards and enforcing mincount requirements.
# I couldn't find a nice way to re-use merging logic for queries but since
merging them is so simple, I let it be and just have a bit of duplicated code
in PivotFacetHelper.
All tests pass. A review would be appreciated.

> 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. Parameter format would look
> like:
> facet.pivot={!query=r1}category,manufacturer
> facet.query={!tag=r1}somequery
> facet.query={!tag=r1}somedate:[NOW-1YEAR TO NOW]
