Vitaliy Zhovtyuk updated SOLR-6351:
-----------------------------------
Attachment: SOLR-6351.patch
Restored FacetPivotSmallTest, was lost between patches.
Added distributed test
org.apache.solr.handler.component.DistributedFacetPivotSmallAdvancedTestcovering
3additional cases
1. Getting pivot stats in string stats field
2. Getting top level stats on pivot stats
3. Pivot stats on each shard are not the same
Added getter to check stats values presence on
org.apache.solr.handler.component.PivotFacetValue#getStatsValues
Whitebox test assertions are not yet completed. Still working on it.
> Let Stats Hang off of Pivots (via 'tag')

> he goal here is basically flip the notion of "stats.facet" on it's head, so
> that instead of asking the stats component to also do some faceting
> (something that's never worked well with the variety of field types and has
> never worked in distributed mode) we instead ask the PivotFacet code to
> compute some stats X for each leaf in a pivot. We'll do this with the
> existing {{stats.field}} params, but we'll leverage the {{tag}} local param
> of the {{stats.field}} instances to be able to associate which stats we want
> hanging off of which {{facet.pivot}}
> Example...
> {noformat}
> facet.pivot={!stats=s1}category,manufacturer
> stats.field={!key=avg_price tag=s1 mean=true}price
> stats.field={!tag=s1 min=true max=true}user_rating
> {noformat}
> ...with the request above, in addition to computing the min/max user_rating
> and mean price (labeled "avg_price") over the entire result set, the
> PivotFacet component will also include those stats for every node of the tree
> it builds up when generating a pivot of the fields "category,manufacturer"
