# Vector Search

Record: `arch:vector-search`
Kind: mechanism
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: contextual
Scope: retrieval, search, RAG
Canonical: https://banes-lab.com/ontology#arch-vector-search

## Repair

- Refactored by: Add Embeddings, Add Vector Index, Tune Retrieval
- Detected by: poor semantic recall
- Violated by: semantic retrieval requirement implemented with only brittle keyword matching
- Measured by: retrieval metrics, [latency](https://banes-lab.com/records/arch/latency.md)
- Enforced by: retrieval evaluation

## requires

- [Embeddings](https://banes-lab.com/records/lex/embeddings.md)
- [Vector Index](https://banes-lab.com/records/lex/vector-index.md)
