Amazon OpenSearch Service now supports automatic semantic enrichment for VPC domains
Amazon OpenSearch Service now supports automatic semantic enrichment for VPC-enabled domains, enabling AI-powered, context-aware search within private networks.
Amazon Web Services announced that Amazon OpenSearch Service now supports automatic semantic enrichment for domains configured within Virtual Private Clouds (VPCs). This feature allows customers to perform AI-driven, context-aware searches without exposing their domains to the public internet, maintaining existing security protocols. Previously limited to non-VPC domains, the capability now extends to private network environments, improving search relevance while preserving network isolation.
Automatic semantic enrichment transforms traditional keyword-based search by interpreting query intent rather than matching exact terms. For instance, a search for 'lightweight laptop for travel' may return results for 'ultrabooks' or 'portable notebooks under 3 lbs' even if those phrases are not explicitly used. The feature automates semantic processing, removing the need for customers to manage machine learning models or integration overhead.
The new capability is available across 11 AWS Regions globally, including US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai, Singapore, Sydney, Tokyo), and Europe (Frankfurt, Ireland, Spain, Stockholm). Customers must ensure their VPC-enabled OpenSearch Service domains are running version 2.19 or later to enable the feature.
To implement automatic semantic enrichment, users must create an index with the feature’s fields configured on their VPC-enabled OpenSearch Service domain. AWS notes that updating to the latest service software version may be required. Detailed guidance is available in the official documentation.
