Reference documentation and code samples for the Discovery Engine v1beta API class ServingConfig.

Configures metadata that is used to generate serving time results (e.g. search results or recommendation predictions). The ServingConfig is passed in the search and predict request and generates results.

CreateTime

public Timestamp CreateTime { get; set; }

Output only. ServingConfig created timestamp.

Property Value
Type	Description
Timestamp

DisplayName

public string DisplayName { get; set; }

Required. The human readable serving config display name. Used in Discovery UI.

This field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

Property Value
Type	Description
string

DissociateControlIds

public RepeatedField<string> DissociateControlIds { get; }

Condition do not associate specifications. If multiple do not associate conditions match, all matching do not associate controls in the list will execute. Order does not matter. Maximum number of specifications is 100.

Can only be set if [SolutionType][google.cloud.discoveryengine.v1beta.SolutionType] is [SOLUTION_TYPE_SEARCH][google.cloud.discoveryengine.v1beta.SolutionType.SOLUTION_TYPE_SEARCH].

Property Value
Type	Description
RepeatedFieldstring

DiversityLevel

public string DiversityLevel { get; set; }

How much diversity to use in recommendation model results e.g. medium-diversity or high-diversity. Currently supported values:

• no-diversity
• low-diversity
• medium-diversity
• high-diversity
• auto-diversity

If not specified, we choose default based on recommendation model type. Default value: no-diversity.

Can only be set if [SolutionType][google.cloud.discoveryengine.v1beta.SolutionType] is [SOLUTION_TYPE_RECOMMENDATION][google.cloud.discoveryengine.v1beta.SolutionType.SOLUTION_TYPE_RECOMMENDATION].

Property Value
Type	Description
string

EmbeddingConfig

public EmbeddingConfig EmbeddingConfig { get; set; }

Bring your own embedding config. The config is used for search semantic retrieval. The retrieval is based on the dot product of [SearchRequest.EmbeddingSpec.EmbeddingVector.vector][google.cloud.discoveryengine.v1beta.SearchRequest.EmbeddingSpec.EmbeddingVector.vector] and the document embeddings that are provided by this EmbeddingConfig. If [SearchRequest.EmbeddingSpec.EmbeddingVector.vector][google.cloud.discoveryengine.v1beta.SearchRequest.EmbeddingSpec.EmbeddingVector.vector] is provided, it overrides this [ServingConfig.embedding_config][google.cloud.discoveryengine.v1beta.ServingConfig.embedding_config].

Property Value
Type	Description
EmbeddingConfig

FilterControlIds

public RepeatedField<string> FilterControlIds { get; }

Filter controls to use in serving path. All triggered filter controls will be applied. Filter controls must be in the same data store as the serving config. Maximum of 20 filter controls.

Property Value
Type	Description
RepeatedFieldstring

GenericConfig

public ServingConfig.Types.GenericConfig GenericConfig { get; set; }

The GenericConfig of the serving configuration.

Property Value
Type	Description
ServingConfigTypesGenericConfig

IgnoreControlIds

public RepeatedField<string> IgnoreControlIds { get; }

Condition ignore specifications. If multiple ignore conditions match, all matching ignore controls in the list will execute. Order does not matter. Maximum number of specifications is 100.

Property Value
Type	Description
RepeatedFieldstring

MediaConfig

public ServingConfig.Types.MediaConfig MediaConfig { get; set; }

The MediaConfig of the serving configuration.

Property Value
Type	Description
ServingConfigTypesMediaConfig

ModelId

public string ModelId { get; set; }

The id of the model to use at serving time. Currently only RecommendationModels are supported. Can be changed but only to a compatible model (e.g. others-you-may-like CTR to others-you-may-like CVR).

Required when [SolutionType][google.cloud.discoveryengine.v1beta.SolutionType] is [SOLUTION_TYPE_RECOMMENDATION][google.cloud.discoveryengine.v1beta.SolutionType.SOLUTION_TYPE_RECOMMENDATION].

Property Value
Type	Description
string

Name

public string Name { get; set; }

Immutable. Fully qualified name projects/{project}/locations/{location}/collections/{collection_id}/engines/{engine_id}/servingConfigs/{serving_config_id}

Property Value
Type	Description
string

OnewaySynonymsControlIds

public RepeatedField<string> OnewaySynonymsControlIds { get; }

Condition oneway synonyms specifications. If multiple oneway synonyms conditions match, all matching oneway synonyms controls in the list will execute. Maximum number of specifications is 100.

Can only be set if [SolutionType][google.cloud.discoveryengine.v1beta.SolutionType] is [SOLUTION_TYPE_SEARCH][google.cloud.discoveryengine.v1beta.SolutionType.SOLUTION_TYPE_SEARCH].

Property Value
Type	Description
RepeatedFieldstring

RankingExpression

public string RankingExpression { get; set; }

The ranking expression controls the customized ranking on retrieval documents. To leverage this, document embedding is required. The ranking expression setting in ServingConfig applies to all search requests served by the serving config. However, if [SearchRequest.ranking_expression][google.cloud.discoveryengine.v1beta.SearchRequest.ranking_expression] is specified, it overrides the ServingConfig ranking expression.

The ranking expression is a single function or multiple functions that are joined by "+".

• ranking_expression = function, { " + ", function }; Supported functions:
• double * relevance_score

• double * dotProduct(embedding_field_path) Function variables: relevance_score: pre-defined keywords, used for measure relevance between query and document. embedding_field_path: the document embedding field used with query embedding vector. dotProduct: embedding function between embedding_field_path and query embedding vector.

  Example ranking expression: If document has an embedding field doc_embedding, the ranking expression could be 0.5 * relevance_score + 0.3 * dotProduct(doc_embedding).

Property Value
Type	Description
string

RedirectControlIds

public RepeatedField<string> RedirectControlIds { get; }

IDs of the redirect controls. Only the first triggered redirect action is applied, even if multiple apply. Maximum number of specifications is 100.

Can only be set if [SolutionType][google.cloud.discoveryengine.v1beta.SolutionType] is [SOLUTION_TYPE_SEARCH][google.cloud.discoveryengine.v1beta.SolutionType.SOLUTION_TYPE_SEARCH].
