Instance Attribute Details

#condition_boost_specs ⇒ `::Array<::Google::Cloud::Retail::V2::SearchRequest::BoostSpec::ConditionBoostSpec>`

Returns Condition boost specifications. If a product 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.

Returns:

(::Array<::Google::Cloud::Retail::V2::SearchRequest::BoostSpec::ConditionBoostSpec>) —
Condition boost specifications. If a product 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.

  # Boost applies to products which match a condition.
  # @!attribute [rw] condition
  #   @return [::String]
  #     An expression which specifies a boost condition. The syntax and
  #     supported fields are the same as a filter expression. See
  #     {::Google::Cloud::Retail::V2::SearchRequest#filter SearchRequest.filter} for
  #     detail syntax and limitations.
  #
  #     Examples:
  #
  #     * To boost products with product ID "product_1" or "product_2", and
  #     color
  #       "Red" or "Blue":
  #         * (id: ANY("product_1", "product_2")) AND (colorFamilies:
  #         ANY("Red","Blue"))
  # @!attribute [rw] boost
  #   @return [::Float]
  #     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 item a big promotion. However, it does not
  #     necessarily mean that the boosted item will be the top result at all
  #     times, nor that other items 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 items.
  #
  #     Setting to -1.0 gives the item a big demotion. However, results that
  #     are deeply relevant might still be shown. The item 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.

#skip_boost_spec_validation ⇒ `::Boolean`

Returns Whether to skip boostspec validation. If this field is set to true, invalid BoostSpec.condition_boost_specs will be ignored and valid BoostSpec.condition_boost_specs will still be applied.
