Reference documentation and code samples for the Discovery Engine v1 API class Control.Types.BoostAction.Types.InterpolationBoostSpec.
Specification for custom ranking based on customer specified attribute
value. It provides more controls for customized ranking than the simple
(condition, boost) combination above.
public Control.Types.BoostAction.Types.InterpolationBoostSpec.Types.AttributeType AttributeType { get; set; }
Optional. The attribute type to be used to determine the boost amount.
The attribute value can be derived from the field value of the
specified field_name. In the case of numerical it is straightforward
i.e. attribute_value = numerical_field_value. In the case of freshness
however, attribute_value = (time.now() - datetime_field_value).
public RepeatedField<Control.Types.BoostAction.Types.InterpolationBoostSpec.Types.ControlPoint> ControlPoints { get; }
Optional. The control points used to define the curve. The monotonic
function (defined through the interpolation_type above) passes through
the control points listed here.
