Amazon OpenSearch Service now supports automatic semantic enrichment for VPC domains

Amazon OpenSearch Service Updates

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.

Automatic semantic enrichment transforms traditional keyword-only search into context-aware retrieval by understanding the meaning behind queries. For example, a search for "lightweight laptop for travel" returns results about "ultrabooks" and "portable notebooks under 3 lbs" even when these exact terms aren't in the query.

This feature is now supported within VPCs (Virtual Private Clouds), enabling customers with stricter network security requirements to improve search relevance while maintaining their existing security posture. No changes to existing VPC configurations are required.

What to do

• Create an index with automatic semantic enrichment fields configured on your VPC-enabled OpenSearch Service domain running OpenSearch version 2.19 or later.
• Update your domain to the latest service software version if necessary.

Automatic semantic enrichment for VPC domains is available across 11 Regions globally: US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai, Singapore, Sydney, Tokyo), and Europe (Frankfurt, Ireland, Spain, Stockholm).
