Expand description
Cross-encoder reranking (spec §7 refinement, 2026-08-27): reads the query and each candidate together, scoring true relevance — the precision lever bi-encoders can’t reach. Opt-in: the model is a sizeable one-time download, so surfaces enable it explicitly.
Structs§
- Fake
Reranker - Test double: scores 1.0 for documents containing the needle, else 0.0.
- Onnx
Reranker - Local ONNX cross-encoder (bge-reranker-base), cached like the embedder.
