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 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

#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.

#serving_config

def serving_config() -> ::String

Returns

(::String) — Required. Full resource name of the format: projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

Before you can request recommendations from your model, you must create at least one serving config for it.

#serving_config=

def serving_config=(value) -> ::String

Parameter

value (::String) — Required. Full resource name of the format: projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

Before you can request recommendations from your model, you must create at least one serving config for it.

Returns

(::String) — Required. Full resource name of the format: projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

#user_event

def user_event() -> ::Google::Cloud::DiscoveryEngine::V1beta::UserEvent

Returns

(::Google::Cloud::DiscoveryEngine::V1beta::UserEvent) — Required. Context about the user, what they are looking at and what action they took to trigger the Recommend request. Note that this user event detail won't be ingested to userEvent logs. Thus, a separate userEvent write request is required for event logging.

Don't set UserEvent.user_pseudo_id or UserEvent.user_info.user_id to the same fixed ID for different users. If you are trying to receive non-personalized recommendations (not recommended; this can negatively impact model performance), instead set UserEvent.user_pseudo_id to a random unique ID and leave UserEvent.user_info.user_id unset.

#user_labels

def user_labels() -> ::Google::Protobuf::Map{::String => ::String}

- Each resource can have multiple labels, up to a maximum of 64.
- Each label must be a key-value pair.
- Keys have a minimum length of 1 character and a maximum length of 63 characters and cannot be empty. Values can be empty and have a maximum length of 63 characters.
- Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes. All characters must use UTF-8 encoding, and international characters are allowed.

def validate_only() -> ::Boolean
