Hoss Man commented on SOLR-6682:
--------------------------------
found while working on SOLR-6351
> EnumField + StatsComponent gives bad toString() for min/max, probably doesn't
> work in distributed search ... definitely needs more tests

> Key: SOLR-6682
> URL: https://issues.apache.org/jira/browse/SOLR-6682
> Project: Solr
> Issue Type: Bug
> Reporter: Hoss Man
>
> when EnumField was added, support was included in StatsComponent for it (via
> the EnumStatsValues) but it doesn't seem to have ever had any tests written
> for it.
> doing some quick manual testing, it seems like the min/max values just wind
> up being the "toString()" value of the EnumFieldValue, so you get a response
> like this...
> {code}
> <lst name="stats">
> <lst name="stats_fields">
> <lst name="hoss">
> <str name="min">org.apache.solr.common.EnumFieldValue:Low</str>
> <str name="max">org.apache.solr.common.EnumFieldValue:High</str>
> <long name="count">2</long>
> <long name="missing">0</long>
> <lst name="facets"/></lst>
> </lst>
> </lst>
> {code}
> we should fix this to return just the stat label, and update the various
> StatsComponent tests to also cover enums & make sure it works as well as
> strings & numbers.
> notably: i'm fairly certain this EnumStatsValues class won't work at all in a
> distributed (stats) request.
