> as mentioned in SOLR-6349, when i started doing perf testing of requesting
> individual stats, i noticed that min (and it turns out max) were slower to
> compute then more complex stats like sum & mean.
> While investigating, i realized that we can also optimize the case where a
> stats.field param is specified, but no stats are computed for example:
> stats.field={!min=$doMin}fieldname&doMin=false
