# Aggregation result

`map string to Aggregation result`

This type represents a dictionary mapping string keys to `Aggregation result` values.

[Read the reference documentation](https://www.elastic.co/docs/explore-analyze/query-filter/aggregations)

## Union types (oneOf)

This type can be one of the following:
