zilliztech/knowhere
Vector search engine inside Milvus, integrating FAISS, HNSW, DiskANN.
Knowhere is a C++ library that serves as the core vector search engine within Milvus. It helps developers integrate advanced vector search capabilities into their applications, taking in vector data and returning relevant search results efficiently. This is primarily used by developers building or customizing vector database systems like Milvus.
328 stars.
Use this if you are a C++ developer working on building or extending a vector database system and need to integrate high-performance vector similarity search algorithms like FAISS, HNSW, or DiskANN.
Not ideal if you are an end-user looking for a ready-to-use vector database or if you primarily work with Python and don't need to deeply customize the underlying C++ search engine.
