}

Strategy for combining structured and vector search results

Variants

Rerank

Vector similarity re-ranks structured results weight: 0.0 = pure structured, 1.0 = pure vector

Fields

weight: f32

FilterThenSearch

Filter with structured query, then search vectors among filtered

SearchThenFilter

Search vectors first, then filter with structured query

RRF

Reciprocal Rank Fusion k: RRF constant (typically 60)

Fields

k: u32

Intersection

Intersection: only return results that match both

Union

Union: return results from either (with combined scores)

Fields

structured_weight: f32

vector_weight: f32
