-### Fusion Strategy - -The `query` command uses **Reciprocal Rank Fusion (RRF)** with position-aware blending: - -1. **Query Expansion**: Original query (×2 for weighting) + 1 LLM variation -2. **Parallel Retrieval**: Each query searches both FTS and vector indexes -3. **RRF Fusion**: Combine all result lists using `score = Σ(1/(k+rank+1))` where k=60 -4. **Top-Rank Bonus**: Documents ranking #1 in any list get +0.05, #2-3 get +0.02 -5. **Top-K Selection**: Take top 30 candidates for reranking -6. **Re-ranking**: LLM scores each document (yes/no with logprobs confidence) -7. **Position-Aware Blending**: - - RRF rank 1-3: 75% retrieval, 25% reranker (preserves exact matches) - - RRF rank 4-10: 60% retrieval, 40% reranker - - RRF rank 11+: 40% retrieval, 60% reranker (trust reranker more) -**Why this approach**: Pure RRF can dilute exact matches when expanded queries don't match. The top-rank bonus preserves documents that score #1 for the original query.
