You can now run OpenSearch version 2.15 in Amazon OpenSearch Service. With OpenSearch 2.15, we have made several improvements in areas of search performance as well as query optimization , and added capabilities to help you to make AI-powered applications with greater flexibility and ease.
This launch includes radial search that allows you to search points within a vector space that reside within a specified maximum distance or minimum score threshold from a query point, offering greater flexibility for various applications like anomaly detection and geospatial searches. In addition to this, this launch includes performance optimizations like two-phase processor for neural sparse search and, conditional scoring logic and optimized data handling for hybrid search. These performance improvements now allow you to run complex queries on larger datasets more efficiently.
OpenSearch now supports reindex workflow, allowing users to enable vector and hybrid search on existing indexes to reduce time and resources spent on re-indexing from source indexes. In addition, you can configure remote models to serve as guardrails to detect harmful, offensive, or inappropriate content (toxicity) more accurately. Finally, a new ML inference processor enables users to enrich ingest pipelines using inferences from OpenSearch-provided pretrained models.
For information on upgrading to OpenSearch 2.15, please see our documentation. OpenSearch 2.15 is now available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
