> When using calcdistinct with large amounts of data the distinctValues field can be extremely large. In cases where the countDistinct is only required it would be helpful if the server did not return distinctValues in the response.
> I'm no expert, but here are some ideas for how the syntax could look.
> {code}
> # Both countDistinct and distinctValues are returned, along with all other stats
> stats.calcdistinct=true&stats.field=myfield
> # Only countDistinct and distinctValues are returned
> stats.calcdistinct=true&stats.field={!countDistinct=true distinctValues=true}myfield
> # Only countDistinct is returned
> stats.calcdistinct=true&stats.field={!countDistinct=true}myfield
> # Only distinctValues is returned
> stats.calcdistinct=true&stats.field={!distinctValues=true}myfield
> {code}
