Reference documentation and code samples for the Discovery Engine v1 API class SearchRequest.Types.BoostSpec.Types.ConditionBoostSpec.Types.BoostControlSpec.
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 SearchRequest.Types.BoostSpec.Types.ConditionBoostSpec.Types.BoostControlSpec.Types.AttributeType AttributeType { get; set; }
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<SearchRequest.Types.BoostSpec.Types.ConditionBoostSpec.Types.BoostControlSpec.Types.ControlPoint> ControlPoints { get; }
The control points used to define the curve. The monotonic function
(defined through the interpolation_type above) passes through the
control points listed here.
