Description

Sometimes it's useful to know the maximum or minimum value of a date field that's passing through a rollup() command. For example in the following expression, the effect would be to portray the freshness of the data for the bucket on which the counts have been generated.

rollup(search(activate2018-tra, q="racecar_id:*", fl="id,presented_date,racecar_id", sort="racecar_id asc",rows=99999),over=racecar_id, max(presented_date),count(*))
