Demystifying Vector Databases: OpenSearch for Semantic Search
Ready to unlock the true potential of your data? We're diving deep into the world of Vector Search with special guest Dotan Horovitz, Senior Developer Advocate at AWS and OpenSearch Ambassador. We break down complex tech into simple, actionable insights for developers and data enthusiasts alike. Dotan guides us through the essentials of vector versus lexical search, revealing why "hybrid search" might be the winning strategy you're looking for. We also explore the cutting edge of multimodal search (searching across images, video, and text) and how to deploy powerful AI agents directly within OpenSearch. Whether you are building the next big GenAI application or just want to understand the mechanics behind semantic search, this conversation is packed with value.
