在你的 Postgres 上為 AI 代理提供圖、向量與文字檢索
透過一致的介面同時查詢圖、向量、全文與混合檢索，不必把多個系統拼湊在一起。
開源引擎 pgGraph 可跨紀錄沿關係遍歷，不必搬移資料即可實現多跳與最短路徑式檢索。
以嵌入為基礎的語意搜尋結合稀疏、全文比對，兼顧語意與精確詞條的查詢需求。
儀表板遊樂場、用於匯入與設定的 CLI，以及強型別 Python SDK，讓原型驗證到正式上線一氣呵成。
Qdrant is an open-source vector search engine and database, written in Rust, for high-performance similarity search in AI applications.
Built entirely in Rust with SIMD and a custom Gridstore storage engine for fast, scalable vector search.
Combine dense and sparse vectors in one query, supporting BM25, SPLADE++ and miniCOIL for keyword-plus-vector retrieval.
Store metadata as JSON and apply advanced filters such as nested, text, geo and has_vector, with filters applied during HNSW traversal.
Asymmetric, scalar and binary quantization reduce memory usage by up to 64x while preserving search quality.
專項更強Pinecone is a managed vector database and AI knowledge platform for building retrieval-augmented generation (RAG), semantic search, and agent memory. It stores vector embeddings at scale, makes writes searchable within seconds with no index tuning, and keeps p99 latency steady as data grows. Pinecone powers products for more than 10,000 customers and over a million developers worldwide.
