RecommendRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)Request message for Recommend method.
| Attributes | |
|---|---|
| Name | Description | 
| serving_config | strRequired. Full resource name of a ServingConfig: projects/*/locations/global/collections/*/engines/*/servingConfigs/*,
   orprojects/*/locations/global/collections/*/dataStores/*/servingConfigs/*One default serving config is created along with your
   recommendation engine creation. The engine ID is used as the
   ID of the default serving config. For example, for Engineprojects/*/locations/global/collections/*/engines/my-engine,
   you can useprojects/*/locations/global/collections/*/engines/my-engine/servingConfigs/my-enginefor your
   RecommendationService.Recommend
   requests. | 
| user_event | google.cloud.discoveryengine_v1beta.types.UserEventRequired. 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. | 
| page_size | intMaximum number of results to return. Set this property to the number of recommendation results needed. If zero, the service chooses a reasonable default. The maximum allowed value is 100. Values above 100 are set to 100. | 
| filter | strFilter for restricting recommendation results with a length limit of 5,000 characters. Currently, only filter expressions on the filter_tagsattribute 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"))IfattributeFilteringSyntaxis set to true under theparamsfield, 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 returns generic
   (unfiltered) popular Documents. If you only want results
   strictly matching the filters, setstrictFilteringtotruein
   RecommendRequest.params
   to receive empty results instead.
   
   Note that the API never returns
   Documents
   withstorageStatusasEXPIREDorDELETEDregardless of filter choices. | 
| validate_only | boolUse validate only mode for this recommendation query. If set to true, a fake model is 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. | 
| params | MutableMapping[str, google.protobuf.struct_pb2.Value]Additional domain specific parameters for the recommendations. Allowed values: - returnDocument: Boolean. If set totrue, the
     associated Document object is returned in
     RecommendResponse.RecommendationResult.document.
   -returnScore: Boolean. If set to true, the
     recommendation score corresponding to each returned
     Document is 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 tofalse, the service returns 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-diversityThis gives request-level control and
       adjusts recommendation results based on Document
       category.
   
   -attributeFilteringSyntax: Boolean. False by default.
     If set to true, thefilterfield is interpreted
     according to the new, attribute-based syntax. | 
| user_labels | MutableMapping[str, str]The user labels applied to a resource must meet the following requirements: - 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. - The key portion of a label must be unique. However, you can use the same key with multiple resources. - Keys must start with a lowercase letter or international character. See `Requirements for labels |
