public enum SearchRequest.Types.BoostSpec.Types.ConditionBoostSpec.Types.BoostControlSpec.Types.AttributeType
Reference documentation and code samples for the Discovery Engine v1beta API enum SearchRequest.Types.BoostSpec.Types.ConditionBoostSpec.Types.BoostControlSpec.Types.AttributeType.
The attribute(or function) for which the custom ranking is to be
applied.
For the freshness use case the attribute value will be the duration
between the current time and the date in the datetime field
specified. The value must be formatted as an XSD dayTimeDuration
value (a restricted subset of an ISO 8601 duration value). The
pattern for this is: [nD][T[nH][nM][nS]].
E.g. 5D, 3DT12H30M, T24H.
Numerical
The value of the numerical field will be used to dynamically update
the boost amount. In this case, the attribute_value (the x value)
of the control point will be the actual value of the numerical
field for which the boost_amount is specified.
