clearFilter()

public RecommendRequest.Builder clearFilter()

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.

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.

clearUserEvent()

public RecommendRequest.Builder clearUserEvent()

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.

containsParams(String key)

public boolean containsParams(String key)

Additional domain specific parameters for the recommendations. Allowed values:

  • returnDocument: Boolean. If set to true, the associated Document object will be returned in RecommendResponse.results.document.

  • 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.

  • (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.

string filter = 4;

Parameter
NameDescription
valueString

The filter to set.

Returns
TypeDescription
RecommendRequest.Builder

This builder for chaining.

setFilterBytes(ByteString value)

public RecommendRequest.Builder setFilterBytes(ByteString value)

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.

string filter = 4;

Parameter
NameDescription
valueByteString

The bytes for filter to set.

setPageSize(int value)

public RecommendRequest.Builder setPageSize(int value)

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.

int32 page_size = 3;

Parameter
NameDescription
valueint

The pageSize to set.

setServingConfig(String value)

public RecommendRequest.Builder setServingConfig(String value)

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.

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

Parameter
NameDescription
valueString

The servingConfig to set.

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

setUserEvent(UserEvent value)

public RecommendRequest.Builder setUserEvent(UserEvent value)

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.

.google.cloud.discoveryengine.v1beta.UserEvent user_event = 2 [(.google.api.field_behavior) = REQUIRED];

Parameter
NameDescription
valueUserEvent
Returns
TypeDescription

setUserEvent(UserEvent.Builder builderForValue)

public RecommendRequest.Builder setUserEvent(UserEvent.Builder builderForValue)

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.

setValidateOnly(boolean value)

public RecommendRequest.Builder setValidateOnly(boolean value)

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.

bool validate_only = 5;

Parameter
NameDescription
valueboolean

The validateOnly to set.
