# Vector DBs & Stores — Global Fix Map A hub to stabilize retrieval pipelines across popular vector stores. Use this page to jump to per-tool guardrails and verify fixes with the same acceptance targets. ## Quick routes to per-store pages - FAISS → [faiss.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/faiss.md) - Chroma → [chroma.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/chroma.md) - Qdrant → [qdrant.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/qdrant.md) - Weaviate → [weaviate.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/weaviate.md) - Milvus → [milvus.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/milvus.md) - pgvector → [pgvector.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/pgvector.md) - Redis Search/Vec → [redis.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/redis.md) - Elasticsearch (ANN) → [elasticsearch.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/elasticsearch.md) - Pinecone → [pinecone.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/pinecone.md) - Typesense → [typesense.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/typesense.md) - Vespa → [vespa.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/VectorDBs_and_Stores/vespa.md) ## When to use this folder - High similarity but wrong meaning. - Citations do not line up with the retrieved section. - Hybrid retrievers underperform a single retriever. - Query casing or analyzer or metric mismatches after deploy. - Index looks healthy yet coverage remains low. ## Acceptance targets for any store - ΔS(question, retrieved) ≤ 0.45 - Coverage of target section ≥ 0.70 - λ_observe stays convergent across 3 paraphrases - E_resonance flat on long windows ## Map symptoms → structural fixes (Problem Map) - **Embedding ≠ Semantic** Wrong-meaning hits despite high similarity. → [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md) - **Retrieval traceability** Snippet/section mismatch or unverifiable citations. → [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) Payload schema → [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) - **Ordering / version skew** Old index or analyzer used at runtime. → [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) · [predeploy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) - **Hybrid collapse / query split** HyDE vs BM25 disagreement, reranker blind spots. → Pattern: [patterns/pattern_query_parsing_split.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md) → Knobs: [rerankers.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) ## 60-second fix checklist (store-agnostic) 1) Lock metrics and analyzers One embedding model per field. One distance function. Same analyzer for write and read. 2) Contract the snippet Require `{snippet_id, section_id, source_url, offsets, tokens}`. Enforce cite-then-explain. → [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) 3) Add deterministic reranking Keep candidate lists from BM25 and ANN. Detect query split. → [rerankers.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) 4) Cold-start and deploy fences Block traffic until index hash, analyzer, and model versions match. → [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) 5) Observability Log ΔS and λ across retrieve → rerank → reason. Alert when ΔS ≥ 0.60. 6) Regression gate Require coverage ≥ 0.70 and ΔS ≤ 0.45 before publish. ## Copy-paste audit prompt ``` I uploaded TXT OS and the WFGY Problem Map pages. Store: . Retrieval: \ with . Audit this query and return: * ΔS(question, retrieved) and λ across retrieve → rerank → reason. * If ΔS ≥ 0.60, choose one minimal structural fix and name the page: embedding-vs-semantic, retrieval-traceability, data-contracts, rerankers. * JSON only: { "citations":\[...], "ΔS":0.xx, "λ":"→|←|<>|×", "next\_fix":"..." } ``` --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | |------|------|--------------| | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + ” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### 🧭 Explore More | Module | Description | Link | |-----------------------|----------------------------------------------------------|----------| | WFGY Core | WFGY 2.0 engine is live: full symbolic reasoning architecture and math stack | [View →](https://github.com/onestardao/WFGY/tree/main/core/README.md) | | Problem Map 1.0 | Initial 16-mode diagnostic and symbolic fix framework | [View →](https://github.com/onestardao/WFGY/tree/main/ProblemMap/README.md) | | Problem Map 2.0 | RAG-focused failure tree, modular fixes, and pipelines | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) | | Semantic Clinic Index | Expanded failure catalog: prompt injection, memory bugs, logic drift | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/SemanticClinicIndex.md) | | Semantic Blueprint | Layer-based symbolic reasoning & semantic modulations | [View →](https://github.com/onestardao/WFGY/tree/main/SemanticBlueprint/README.md) | | Benchmark vs GPT-5 | Stress test GPT-5 with full WFGY reasoning suite | [View →](https://github.com/onestardao/WFGY/tree/main/benchmarks/benchmark-vs-gpt5/README.md) | | 🧙‍♂️ Starter Village 🏡 | New here?
