Hybrid Retrieval v2: Qwen Embeddings, BM25, and RRF with a FastEmbed Reranker

Dense vectors miss exact identifiers. Here's the hybrid Qdrant setup I run: Qwen3 embeddings, BM25 sparse vectors, RRF fusion, and a CPU FastEmbed reranker.

I Benchmarked My Homelab Memory Stack: Hybrid Search + Local Reranker Took LoCoMo from 63% to 80%

How adding BM25 hybrid search and a local BGE reranker to a vector-only agent memory stack moved LoCoMo accuracy from 63% to 80%, and what it cost in latency.
