Amazon OpenSearch Service now brings automatic semantic enrichment to managed clusters, matching the capability we launched for OpenSearch Serverless earlier this year. This feature allows you to leverage the power of semantic search with minimal configuration effort.
Traditional lexical search only matches exact phrases, often missing relevant content. Automatic semantic enrichment understands context and meaning, delivering more relevant results. For example, a search for “eco-friendly transportation options” finds matches about “electric vehicles” or “public transportation”—even when these exact terms aren’t present. This new capability handles all semantic processing automatically, eliminating the need to manage machine learning models. It supports both English-only and multi-lingual variants, covering 15 languages including Arabic, French, Hindi, Japanese, Korean, and more. You pay only for actual usage during data ingestion, billed as OpenSearch Compute Unit (OCU) – Semantic Search. View the pricing page for cost details and a pricing example.
This feature is now available for Amazon OpenSearch Service domains running OpenSearch version 2.19 or later. Currently, this feature supports non-VPC domains in the following AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), Europe (Ireland), and Europe (Stockholm).
