Constructors

constructor(field: QueryField? = null, alias: String, missingKey: String? = null, expression: AggregationExpression? = null, scope: AggregationGroupScope? = null)

Properties

alias

open override val alias: String

expression

val expression: AggregationExpression?

field

open override val field: QueryField?

The grouped field; null only for a TERMS or HISTOGRAM group whose input is an expression.

missingKey

val missingKey: String?

scope

open override val scope: AggregationGroupScope?

Where field is read when the query expands elements: null (the innermost element, relative to its container) or AggregationGroupScope.ROOT (a root field, by its absolute path), so a count of elements can be grouped by a field of the record they belong to, such as its creation day. Without elements both read the root.
