 The --summary argument returns for each key used in the store, the count of files which
 used the key, and the minimum and maximum (string-ordered) value for each.

-all values:

-fn.owner        dtucker

 The --values flag can give you the list of all distinct values for a given key in the store. 
 You can request multiple keys by giving a comma-separated list to the --values parameter.
