Given an index where it contains user login documents, so there is a userid field and a time field. Can I query for all the last login document for each user?

I don't want to build a list of each user on the query because it could be huge.

Thanks!

There's an example of that very question here: [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/search-aggregations-bucket-terms-aggregation.html#\_filtering\_values\_with\_partitions](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/search-aggregations-bucket-terms-aggregation.html#_filtering_values_with_partitions)

Thanks. Maybe its trivial but I'm not looking for the last login time, but rather the entire login document for that time. It would be nice to get that in a single query.

Add a top\_hits agg with size:1 sorted by date, reverse order. The partition advice still stands if you have a lot of users.
