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
• Chroma → chroma.md
• Qdrant → qdrant.md
• Weaviate → weaviate.md
• Milvus → milvus.md
• pgvector → pgvector.md
• Redis Search/Vec → redis.md
• Elasticsearch (ANN) → elasticsearch.md
• Pinecone → pinecone.md
• Typesense → typesense.md
• Vespa → 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

• Retrieval traceability
  Snippet/section mismatch or unverifiable citations.
  → retrieval-traceability.md
  Payload schema → data-contracts.md

• Ordering / version skew
  Old index or analyzer used at runtime.
  → bootstrap-ordering.md · predeploy-collapse.md

• Hybrid collapse / query split
  HyDE vs BM25 disagreement, reranker blind spots.
  → Pattern: patterns/pattern_query_parsing_split.md
  → Knobs: 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

3. Add deterministic reranking
   Keep candidate lists from BM25 and ANN. Detect query split.
   → rerankers.md

4. Cold-start and deploy fences
   Block traffic until index hash, analyzer, and model versions match.
   → 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: <name>. Retrieval: \<bm25/ann/hybrid> with <distance>.

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":"..." }
