Method Detail

getServingConfig

String getServingConfig()

 Required. Full resource name of a
 [ServingConfig][google.cloud.discoveryengine.v1alpha.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 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.
 

string serving_config = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns:

The servingConfig.

getServingConfigBytes

com.google.protobuf.ByteString getServingConfigBytes()

 Required. Full resource name of a
 [ServingConfig][google.cloud.discoveryengine.v1alpha.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 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.
 

string serving_config = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns:

The bytes for servingConfig.

hasUserEvent

boolean hasUserEvent()

 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.
 

.google.cloud.discoveryengine.v1alpha.UserEvent user_event = 2 [(.google.api.field_behavior) = REQUIRED];

Returns:

Whether the userEvent field is set.

getUserEvent

UserEvent getUserEvent()

 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.
 

.google.cloud.discoveryengine.v1alpha.UserEvent user_event = 2 [(.google.api.field_behavior) = REQUIRED];

Returns:

The userEvent.

getUserEventOrBuilder

UserEventOrBuilder getUserEventOrBuilder()

 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.
 

.google.cloud.discoveryengine.v1alpha.UserEvent user_event = 2 [(.google.api.field_behavior) = REQUIRED];

getPageSize

int getPageSize()

 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.
 

int32 page_size = 3;

Returns:

The pageSize.

getFilter

String getFilter()

 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.
 

string filter = 4;

Returns:

The filter.

getFilterBytes

com.google.protobuf.ByteString getFilterBytes()

 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.
 

string filter = 4;

Returns:

The bytes for filter.

getValidateOnly

boolean getValidateOnly()

 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.
 

bool validate_only = 5;

Returns:

The validateOnly.

getParamsCount

int getParamsCount()

 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`

     *  `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.
