Hoss Man created SOLR-6682:
------------------------------
Summary: 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.
