Imagine we have an ecommerce, and an index with a document per every sale, with **user** and **product** fields. For each user I'd like to always know which is the last product they bought.  
How could we tackle that?

Have a look at this:

[https://www.elastic.co/guide/en/elasticsearch/reference/7.7/transform-painless-examples.html#painless-top-hits](https://www.elastic.co/guide/en/elasticsearch/reference/7.7/transform-painless-examples.html#painless-top-hits)

This is part of the 7.7 documentation, however should work in older versions, too.
