	// `projects/*/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 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][google.cloud.discoveryengine.v1alpha.RecommendationService.Recommend]
	// requests.
	ServingConfig string `protobuf:"bytes,1,opt,name=serving_config,json=servingConfig,proto3" json:"serving_config,omitempty"`
	// 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][google.cloud.discoveryengine.v1alpha.UserEvent.user_pseudo_id]
	// or
	// [UserEvent.user_info.user_id][google.cloud.discoveryengine.v1alpha.UserInfo.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][google.cloud.discoveryengine.v1alpha.UserEvent.user_pseudo_id]
	// to a random unique ID and leave
	// [UserEvent.user_info.user_id][google.cloud.discoveryengine.v1alpha.UserInfo.user_id]
	// unset.
	UserEvent *UserEvent `protobuf:"bytes,2,opt,name=user_event,json=userEvent,proto3" json:"user_event,omitempty"`
	// Maximum 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.
	PageSize int32 `protobuf:"varint,3,opt,name=page_size,json=pageSize,proto3" json:"page_size,omitempty"`
	// 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 returns generic
	// (unfiltered) popular Documents. If you only want results strictly matching
	// the filters, set `strictFiltering` to `true` in
	// [RecommendRequest.params][google.cloud.discoveryengine.v1alpha.RecommendRequest.params]
	// to receive empty results instead.
	//
	// Note that the API never returns
	// [Document][google.cloud.discoveryengine.v1alpha.Document]s with
	// `storageStatus` as `EXPIRED` or `DELETED` regardless of filter choices.
	Filter string `protobuf:"bytes,4,opt,name=filter,proto3" json:"filter,omitempty"`
	// Use 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.
	ValidateOnly bool `protobuf:"varint,5,opt,name=validate_only,json=validateOnly,proto3" json:"validate_only,omitempty"`
	// Additional domain specific parameters for the recommendations.
	//
	// Allowed values:
	//
	//   - `returnDocument`: Boolean. If set to `true`, the associated Document
	//     object is returned in
	//     [RecommendResponse.RecommendationResult.document][google.cloud.discoveryengine.v1alpha.RecommendResponse.RecommendationResult.document].
	//   - `returnScore`: Boolean. If set to true, the recommendation score
	//     corresponding to each returned Document is set in
	//     [RecommendResponse.RecommendationResult.metadata][google.cloud.discoveryengine.v1alpha.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
	//
	//	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-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.
	Params map[string]*structpb.Value `protobuf:"bytes,6,rep,name=params,proto3" json:"params,omitempty" protobuf_key:"bytes,1,opt,name=key,proto3" protobuf_val:"bytes,2,opt,name=value,proto3"`
