No fuss multi-index hybrid vector database / search engine SemaDB is a multi-index, multi-vector, document-based vector database / search engine. It is designed to offer a clear and easy-to-use JSON RESTful API. The original components of SemaDB were built for a knowledge-management project at Semafind before it was developed into a standalone project. The goal is to provide a simple, modern, and efficient search engine that can be used in a variety of applications.
