I have a index pattern with data with files for every business day(i have a run time field named business time/day) which is the business day and time everyday.

Now I want to show a visualization/dashboard to get the batch duration(I have a field) on the first file on a daily basis(every day in a certain time in a business time) and the last file in the same business day.

So I just want the first file and last file loaded every day on a daily basis(which is in the data everyday)

How would I approach this? a scripted field? Not sure? thank you!

You could do that with a [top hits aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/8.3/search-aggregations-metrics-top-hits-aggregation.html), and sort asc/desc on timestamp to get each one.
