[jira] [Commented] (SOLR-6351) Let Stats Hang off of Pivots (via 'tag')

["Hoss Man (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-6351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14130904#comment-14130904 ] 

Hoss Man commented on SOLR-6351:
--------------------------------

bq. SimpleStats will need refactored: ...

FWIW: I've started incorporating some of these ideas into the bug fix i'm doing in SOLR-6507 since it addresses the root problem in that bug and gives us a better place to build on for issues like this.

> 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"
