Hoss Man commented on SOLR-4212:
--------------------------------
I haven't had a chance to review this patch, but in response to a dev@lucene
thread about it...
bq. Base idea is to have something like:
{{facet.pivot=field1,field2,field3f.field2.facet.pivot.q=somequery&f.field3.facet.pivot.q=somedate:\[NOW-1YEAR
TO NOW\]&f.field3.facet.pivot.q=someotherquery}} ... Which would add results
similar to facet queries, at the appropriate level in the pivots.
>From a functionality standpoint, what you are setting out to do here seems
>like a great idea -- but personally i think that syntax looks really
>cumbersome?
>From a user API standpoint, It seems your gola here would gel really well with
>the syntax i proposed in SOLR-6348/(SOLR-6351,SOLR-6352,SOLR-6353) if you
>think about it in terms of "hanging query facets off of pivots" ... ie:
{noformat}
facet.pivot={!query=r1}category,manufacturer
facet.query={!tag=r1}somequery
facet.query={!tag=r1}somedate:[NOW-1YEAR TO NOW]
{noformat}
that seems like it might be cleaner, and fit better with some of the other
ongoing work, what do you think?

> 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 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.
