//! The aggregations in this family compute metrics based on values extracted in one way or another from the documents that
//! are being aggregated. The values are typically extracted from the fields of the document (using the field data), but
//! can also be generated using scripts.
//!
//! Numeric metrics aggregations are a special type of metrics aggregation which output numeric values. Some aggregations output
//! a single numeric metric (e.g. `avg`) and are called `single-value numeric metrics aggregation`, others generate multiple
//! metrics (e.g. `stats`) and are called `multi-value numeric metrics aggregation`. The distinction between single-value and
//! multi-value numeric metrics aggregations plays a role when these aggregations serve as direct sub-aggregations of some
//! bucket aggregations (some bucket aggregations enable you to sort the returned buckets based on the numeric metrics in each bucket).
