I have an Elasticsearch query that creates aggregations based on specific search terms. Within each bucket of the date histogram aggregation, the doc\_count gives the total number of documents matching the search criteria.

What I would also like is the total number of background documents for that time period so that I can do a ratio comparison. For instance, if my search term is "president" and the doc\_count in one of the buckets is 45,000, I'd like to get back the total number of documents for that time period as well.

I know this could be achieved by doing two separate aggregations, but I was curious if there was any built-in functionality to get the bg\_count for date histogram aggregations (all documents in that time range, not just matching documents).

Thank you!

a second aggregation using the [global agg](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/search-aggregations-bucket-global-aggregation.html) sounds like the way to go here for me.
