Description

smolloy asked a great question in SOLR-6351...

One more question around this, which applies for SOLR-6353 and SOLR-4212 as well. Should we have a syntax to apply stats/queries/ranges only at specific levels in the pivot hierarchy? It would reduce amount of computation and size of response for cases where you only need it at a specific level (usually last level I guess).

I'm splitting this off into it's own Sub-task for further discussion.

For now, the "stats" localparam must be a single tag, and the "work around" is to add a common tag to all stats you want to use.

ie, this will cause an error...

stats.field={!tag=tagA}price
stats.field={!tag=tagB}popularity
stats.field={!tag=tagB}clicks
facet.pivot={!stats=tagA,tagB}xxx,yyy,zz

but this will work...

stats.field={!tag=tagA,tagPivot}price
stats.field={!tag=tagB,tagPivot}popularity
stats.field={!tag=tagB,tagPivot}clicks
facet.pivot={!stats=tagPivot}xxx,yyy,zz
