Zhang Yuan commented on LUCENE-7590:
------------------------------------
[~shaie] I'm a little confused about the description defined here.
{code}
public LongDocValuesStats(String description) {
super(description, Long.MAX_VALUE, Long.MIN_VALUE);
}
{code}
it was in turn passed to NumericDocValueStats as the name of DV field.
Why not use the {{field}} as the name of parameter in LongDocValuesStats?

> I think it can be useful to have DocValues statistics helpers, that can allow
> users to query for the min/max/avg etc. stats of a DV field. In this issue
> I'd like to cover numeric DV, but there's no reason not to add it to other DV
> types too.
