-------------------------------------
no for 7.x you need to handle -1 case for stats, just like MultiTerms currently
does.

> {{IndexSearcher.collectionStatistics(field)}} can do a fair amount of work
> because with each invocation it will call {{MultiFields.getTerms(...)}}. The
> effects of this are aggravated for queries with many fields since each field
> will want statistics, and also aggravated when there are many segments.
