#condition_boost_specs ⇒ ::Array<::Google::Cloud::Dialogflow::V2::SearchKnowledgeRequest::SearchConfig::BoostSpecs::BoostSpec::ConditionBoostSpec>

Returns Optional. Condition boost specifications. If a document matches multiple conditions in the specifictions, boost scores from these specifications are all applied and combined in a non-linear way. Maximum number of specifications is 20.

class BoostSpec
  include ::Google::Protobuf::MessageExts
  extend ::Google::Protobuf::MessageExts::ClassMethods

  # Boost applies to documents which match a condition.
  # @!attribute [rw] condition
  #   @return [::String]
  #     Optional. An expression which specifies a boost condition. The
  #     syntax and supported fields are the same as a filter expression.
  #     Examples:
  #
  #     * To boost documents with document ID "doc_1" or "doc_2", and
  #     color
  #       "Red" or "Blue":
  #         * (id: ANY("doc_1", "doc_2")) AND (color: ANY("Red","Blue"))
  # @!attribute [rw] boost
  #   @return [::Float]
  #     Optional. Strength of the condition boost, which should be in [-1,
  #     1]. Negative boost means demotion. Default is 0.0.
  #
  #     Setting to 1.0 gives the document a big promotion. However, it does
  #     not necessarily mean that the boosted document will be the top
  #     result at all times, nor that other documents will be excluded.
  #     Results could still be shown even when none of them matches the
  #     condition. And results that are significantly more relevant to the
  #     search query can still trump your heavily favored but irrelevant
  #     documents.
  #
  #     Setting to -1.0 gives the document a big demotion. However, results
  #     that are deeply relevant might still be shown. The document will
  #     have an upstream battle to get a fairly high ranking, but it is not
  #     blocked out completely.
  #
  #     Setting to 0.0 means no boost applied. The boosting condition is
  #     ignored.
  # @!attribute [rw] boost_control_spec
  #   @return [::Google::Cloud::Dialogflow::V2::SearchKnowledgeRequest::SearchConfig::BoostSpecs::BoostSpec::ConditionBoostSpec::BoostControlSpec]
  #     Optional. Complex specification for custom ranking based on
  #     customer defined attribute value.
  class ConditionBoostSpec
    include ::Google::Protobuf::MessageExts
    extend ::Google::Protobuf::MessageExts::ClassMethods

    # Specification for custom ranking based on customer specified
    # attribute
    # value. It provides more controls for customized ranking than the
    # simple (condition, boost) combination above.
    # @!attribute [rw] field_name
    #   @return [::String]
    #     Optional. The name of the field whose value will be used to
    #     determine the boost amount.
    # @!attribute [rw] attribute_type
    #   @return [::Google::Cloud::Dialogflow::V2::SearchKnowledgeRequest::SearchConfig::BoostSpecs::BoostSpec::ConditionBoostSpec::BoostControlSpec::AttributeType]
    #     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).
    # @!attribute [rw] interpolation_type
    #   @return [::Google::Cloud::Dialogflow::V2::SearchKnowledgeRequest::SearchConfig::BoostSpecs::BoostSpec::ConditionBoostSpec::BoostControlSpec::InterpolationType]
    #     Optional. The interpolation type to be applied to connect the
    #     control points listed below.
    # @!attribute [rw] control_points
    #   @return [::Array<::Google::Cloud::Dialogflow::V2::SearchKnowledgeRequest::SearchConfig::BoostSpecs::BoostSpec::ConditionBoostSpec::BoostControlSpec::ControlPoint>]
    #     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.
    class BoostControlSpec
      include ::Google::Protobuf::MessageExts

        # 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:
