With semantic search, you improve the relevance of retrieved results using language-based embeddings on search documents. With OpenSearch Service’s vector database capabilities, you can implement semantic search, Retrieval Augmented Generation (RAG) with LLMs, recommendation engines, and search rich media. Using OpenSearch Service as a vector database OpenSearch’s k-NN plugin provides core vector database functionality for OpenSearch, so when your customer searches for “a cozy place to sit by the fire” in your catalog, you can encode that prompt and use OpenSearch to perform a nearest neighbor query to surface that 8-foot, blue couch with designer arranged photographs in front of fireplaces. It also provides other database functionality like managing vector data alongside other data types, workload management, access control and more. Sophisticated embedding models can support multiple modalities, for instance, encoding the image and text of a product catalog and enabling similarity matching on both modalities.Ī vector database provides efficient vector similarity search by providing specialized indexes like k-NN indexes. By searching for the vectors nearest to an encoded document - k-nearest neighbor (k-NN) search - you can find the most semantically similar documents. An embedding model, for instance, could encode the semantics of a corpus. Among them are the use of embedding models, a type of model that can encode a large body of data into an n-dimensional space where each entity is encoded into a vector, a data point in that space, and organized such that similar entities are closer together. In recent years, machine learning (ML) techniques have become increasingly popular to enhance search. The problem is that couch manufacturers probably didn’t use the words “cozy,” “place,” “sit,” and “fire” in their product titles or descriptions.
You go to, and you type “a cozy place to sit by the fire.” Unfortunately, if you run that search on, you get items like fire pits, heating fans, and home decorations-not what you intended. Let’s say you want to buy a couch in order to spend cozy evenings with your family around the fire. We’ve all become used to the “search box” interface, where you type some words, and the search engine brings back results based on word-to-word matching. Along the way, you use OpenSearch to gather information in support of achieving that goal (or maybe the information is the original goal). Amazon OpenSearch Service is a fully managed service that makes it simple to deploy, scale, and operate OpenSearch in the AWS Cloud.Īs an end-user, when you use OpenSearch’s search capabilities, you generally have a goal in mind-something you want to accomplish. It comprises a search engine, OpenSearch, which delivers low-latency search and aggregations, OpenSearch Dashboards, a visualization and dashboarding tool, and a suite of plugins that provide advanced capabilities like alerting, fine-grained access control, observability, security monitoring, and vector storage and processing.
