Histogram bucket first and last record

Elastic Stack Elasticsearch
1

Hi

I am using ES 6.6.0

I have time series cumulative data, i want to do histogram on the data with time being the field and get first and last records in each bucket. How can we do this?

One crude way am thinking is, apply min and max on timestamp, so that i get first and last records, but how do I extract other fields inside these two records?

take a look at the top hits aggregation
