Amazon OpenSearch Service now supports automatic semantic enrichment for VPC domains

Amazon OpenSearch Service now extends automatic semantic enrichment to VPC-enabled domains, allowing customers with private network configurations to leverage AI-powered semantic search without exposing their domains to the public internet.

• Transforms keyword-only search into context-aware retrieval by understanding query meaning
• Handles all semantic processing automatically without self-managing ML models
• Previously available only on non-VPC domains; now supported within VPCs
• No changes to existing VPC configurations required
• Available across 11 regions globally including US, Asia Pacific, and Europe
• Requires OpenSearch version 2.19 or later

Customers with stricter network security requirements can now improve search relevance while maintaining their existing security posture.
