Previously limited to public domains, automatic semantic enrichment now operates within VPCs, allowing customers with restrictive network policies to leverage context-aware semantic search that interprets query intent beyond keywords. This improves search relevance by delivering results with equivalent meanings even when exact terms differ.
The feature requires OpenSearch version 2.19 or later and is available in 11 global AWS regions. It integrates seamlessly with existing VPC configurations without requiring network changes, thus maintaining security while boosting search quality for sensitive deployments.
