Methods

#filter

def filter() -> ::String
Returns
  • (::String) — Filter for restricting recommendation results with a length limit of 5,000 characters. Currently, only filter expressions on the filter_tags attribute is supported.

    Examples:

    • (filter_tags: ANY("Red", "Blue") OR filter_tags: ANY("Hot", "Cold"))
    • (filter_tags: ANY("Red", "Blue")) AND NOT (filter_tags: ANY("Green"))

    If attributeFilteringSyntax is set to true under the params field, then attribute-based expressions are expected instead of the above described tag-based syntax. Examples:

    • (launguage: ANY("en", "es")) AND NOT (categories: ANY("Movie"))
    • (available: true) AND (launguage: ANY("en", "es")) OR (categories: ANY("Movie"))

    If your filter blocks all results, the API will return generic (unfiltered) popular Documents. If you only want results strictly matching the filters, set strictFiltering to True in RecommendRequest.params to receive empty results instead.

    Note that the API will never return Documents with storageStatus of EXPIRED or DELETED regardless of filter choices.

#filter=

def filter=(value) -> ::String
Parameter
  • value (::String) — Filter for restricting recommendation results with a length limit of 5,000 characters. Currently, only filter expressions on the filter_tags attribute is supported.

#page_size

def page_size() -> ::Integer
Returns
  • (::Integer) — Maximum number of results to return. Set this property to the number of recommendation results needed. If zero, the service will choose a reasonable default. The maximum allowed value is 100. Values above 100 will be coerced to 100.

#page_size=

def page_size=(value) -> ::Integer
Parameter
  • value (::Integer) — Maximum number of results to return. Set this property to the number of recommendation results needed. If zero, the service will choose a reasonable default. The maximum allowed value is 100. Values above 100 will be coerced to 100.

#params

def params() -> ::Google::Protobuf::Map{::String => ::Google::Protobuf::Value}
Returns
  • (::Google::Protobuf::Map{::String => ::Google::Protobuf::Value}) —

    Additional domain specific parameters for the recommendations.

    Allowed values:

    • returnDocument: Boolean. If set to true, the associated Document object will be returned in RecommendResponse.RecommendationResult.document.
    • returnScore: Boolean. If set to true, the recommendation 'score' corresponding to each returned Document will be set in RecommendResponse.RecommendationResult.metadata. The given 'score' indicates the probability of a Document conversion given the user's context and history.
    • strictFiltering: Boolean. True by default. If set to false, the service will return generic (unfiltered) popular Documents instead of empty if your filter blocks all recommendation results.
    • diversityLevel: String. Default empty. If set to be non-empty, then it needs to be one of:
      • no-diversity
      • low-diversity
      • medium-diversity
      • high-diversity
      • auto-diversity This gives request-level control and adjusts recommendation results based on Document category.
    • attributeFilteringSyntax: Boolean. False by default. If set to true, the filter field is interpreted according to the new, attribute-based syntax.

#serving_config

def serving_config() -> ::String
Returns
  • (::String) — Required. Full resource name of a ServingConfig: projects/*/locations/global/collections/*/engines/*/servingConfigs/*, or projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

    One default serving config is created along with your recommendation engine creation. The engine ID will be used as the ID of the default serving config. For example, for Engine projects/*/locations/global/collections/*/engines/my-engine, you can use projects/*/locations/global/collections/*/engines/my-engine/servingConfigs/my-engine for your RecommendationService.Recommend requests.

#validate_only

def validate_only() -> ::Boolean
Returns
  • (::Boolean) — Use validate only mode for this recommendation query. If set to true, a fake model will be used that returns arbitrary Document IDs. Note that the validate only mode should only be used for testing the API, or if the model is not ready.
