Crafting a hybrid geospatial RAG application with Elastic and Amazon Bedrock

The blog post by Udayasimha Theepireddy, Srinivas Pendyala, and Ayan Ray explores the development of a hybrid geospatial Retrieval Augmented Generation (RAG) application using Elasticsearch and Amazon Bedrock. This application aims to enhance real estate searches by integrating lexical, geospatial, and vector similarity search capabilities to create an intelligent assistant capable of providing personalized property recommendations. The post details the architecture and implementation steps, highlighting the role of technologies such as Elastic's vector database for handling query embeddings, Amazon Bedrock's generative AI capabilities, and AWS services like Lambda and Location Service for geocoding and data retrieval. The integration of these technologies facilitates sophisticated geospatial searches, allowing for contextual and relevant responses by leveraging named entity recognition and data augmentation through AWS Data Exchange. Additionally, the post provides a GitHub repository for hands-on experimentation and emphasizes the benefits and considerations of using third-party AI tools in building scalable, enterprise-level applications.
