Developers using Discovery Engine's federated search can now precisely control data store scope. The GoogleCloudDiscoveryengineV1DataStoreFederatedSearchConfigNotebooklmConfig (and its alpha/beta counterparts) introduces a new notebooks array property. This allows you to restrict a data store to specific notebook resources, ensuring search results are confined to relevant content.
For fine-tuning search relevance, the GoogleCloudDiscoveryengineV1alphaFieldConfig schema now includes partialMatchableOption and prefixMatchableOption. These new enum fields provide granular control over how field values are matched during searches, enabling more precise indexing and query behavior.
Feedback mechanisms have also been enhanced. The GoogleCloudDiscoveryengineV1FeedbackConversationInfo schema gains stepSeqNum and trajectoryId properties, offering more detailed context for agent task turns. Additionally, GOOGLE_AGENTSPACE_DESKTOP is now a recognized feedbackSource in GoogleCloudDiscoveryengineV1Feedback.
