[jira] [Commented] (SOLR-11706) JSON FacetModule can't compute stats (min,max,etc...) on multivalued fields

["Munendra S N (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-11706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16981752#comment-16981752 ] 

Munendra S N commented on SOLR-11706:
-------------------------------------

 [^SOLR-11706.patch] 
This patch contains aggregation support on multi-valued fields.
These are the following aggregations included here: min, max, avg, min, max, sum, sumsq, stddev, variance. 
{{percentile}} doesn't yet have support for multi-valued fields (Probably will handle in separate issue)

I have included {{TestJsonFacets}} tests shared above but haven't included StatsComponentTest changes. This is because of following reasons:
* min/max for numeric fields in Stats is always double but in JSON facets, fieldType is respected
* Value type varies for some aggregation. For example, countDistinct is long whereas unique aggregation value is int/long based on single-shard or multi-shard respectively SOLR-11775
* corrected vs uncorrected stddev SOLR-11725

SOLR-12559 is not resolved but I suppose that can be taken up separately/in next phase

> While trying to write some tests demonstrating equivalences between the StatsComponent and the JSON FacetModule i discovered that the FacetModules stat functions (min, max, etc...) don't seem to work on multivalued fields.
> Based on the stack traces, i gather the problem is because the FacetModule seems to rely exclusively on using the "Function" parsers to get a value source -- apparently w/o any other method of accumulating numeric stats from multivalued (numeric) DocValues?
