TopK is an innovative document database that operates in a cloud-native environment with a serverless framework, specifically tailored for enhancing search applications. This system integrates both vector search—viewing vectors as a distinct data type—and traditional keyword search using the BM25 model within a cohesive interface. TopK's advanced query expression language empowers developers to construct dependable applications across various domains, such as semantic, retrieval-augmented generation (RAG), and multi-modal applications, without the complexity of managing multiple databases or services. Furthermore, the comprehensive retrieval engine being developed will facilitate document transformation by automatically generating embeddings, enhance query comprehension by interpreting metadata filters from user inquiries, and implement adaptive ranking by returning "relevance feedback" to TopK, all seamlessly integrated into a single platform for improved efficiency and functionality. This unification not only simplifies development but also optimizes the user experience by delivering precise and contextually relevant search results.
