Amazon OpenSearch Service has long supported both lexical and vector search, since the introduction of its kNN plugin in 2020. With recent developments in generative AI, including AWS’s launch of Amazon Bedrock earlier in 2023, you can now use Amazon Bedrock-hosted models in conjunction with the vector database capabilities of OpenSearch Service, allowing you to implement semantic search, retrieval augmented generation (RAG), recommendation engines, and rich media search based on high-quality vector search. The recent launch of the vector engine for Amazon OpenSearch Serverless makes it even easier to deploy such solutions.

When organizations set out to build machine learning (ML) applications such as natural language processing (NLP) systems, recommendation engines, or search-based systems, often times k-Nearest Neighbor (k-NN) search will be used at some point […]

Amazon OpenSearch Service supports a highly performant, integrated anomaly detection engine that enables the real-time identification of anomalies in streaming data. Last year, we released high-cardinality anomaly detection (HCAD) to detect individual entities’ anomalies. With the 1.1 release, we have allowed you to monitor a million entities with steady, predictable performance. HCAD is easiest when […]

Amazon OpenSearch Service provides an event alerting feature within OpenSearch Dashboards. To use this feature, you work with monitors (scheduled jobs) that have triggers (specific conditions) that you set, telling the monitor when it should send an alert. An alert is a notification that the triggering condition occurred. When a trigger fires, the monitor takes action, sending a message to your destination. This post uses a simulated IoT device farm to generate and send data to Amazon OpenSearch Service.
