Expert guide for high-performance Vector Databases, Deep RAG architectures, pgvector 0.8+ HNSW, Reciprocal Rank Fusion (RRF), Cross-Encoder Re-ranking, and Late Chunking / Panduan ahli Vector DB, arsitektur Deep RAG, pgvector HNSW, RRF, dan Re-ranking.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## English
### Purpose & Overview
Production-grade architectural guide for Vector Databases (PostgreSQL `pgvector 0.8+`, Qdrant, LanceDB, Pinecone), Deep RAG indexing strategies, HNSW iterative search, **Reciprocal Rank Fusion (RRF)** hybrid retrieval, **Cross-Encoder Re-ranking** (Cohere Rerank v3, FlashRank, BGE-Reranker-v2), and **Late Chunking** to eliminate context fragmentation.
### Key Capabilities
1. **pgvector 0.8+ & HNSW Indexing**: High-dimensional vector storage, cosine/inner-product/L2 distance metric tuning, and iterative HNSW index scans with metadata filtering.
2. **Reciprocal Rank Fusion (RRF)**: Combining sparse keyword BM25 ranks with dense semantic vector ranks using $RRF(d) = \sum \frac{1}{k + rank(d)}$, far outperforming naive linear score weighting.
3. **Cross-Encoder Re-ranking**: Two-stage retrieval pipeline: retrieve Top-50 candidates via fast hybrid search, then re-rank down to Top-5 using a cross-encoder model to maximize NDCG@10.

How to install
mdr add roedyrustam/vibes-plug/vector-db-rag-expert@sha256:0f1eca542b607dd8The line at the top of this page pins the label v4.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
