Vector search is a transformative technology that addresses the limitations of traditional keyword-based search systems by focusing on the conceptual and semantic meaning behind queries, rather than just the exact words used. It uses AI-generated numerical representations, known as vector embeddings, to find results based on meaning, enabling more relevant outcomes even when keywords do not match. This capability is foundational for modern AI applications, powering features like personalized recommendations, multimodal searches, and enhancing the accuracy of AI models through Retrieval-Augmented Generation (RAG). Vector search is particularly effective in handling unstructured data, which constitutes the majority of global data, by converting it into uniform vector representations for scalable indexing and retrieval. In practice, it often combines with traditional keyword search and metadata filtering in hybrid approaches to deliver precise and contextually relevant results, exemplifying its role in advanced search solutions. The choice between using a specialized vector database or integrating vector capabilities into a unified data platform significantly impacts operational complexity and performance, with unified platforms offering streamlined operations by eliminating data silos and enabling combined semantic and structured queries.
