Enum FuseStrategy 

pub enum FuseStrategy {
    Rrf {
        k: usize,
    },
    Weighted {
        weights: Vec<f64>,
    },
    Union,
}

Fusion strategy for combining sub-query result lists.

Mirrors FusionStrategy at the IR level so that the query plan is self-contained and serialisable without depending on runtime fusion internals.

Variants

Rrf

Reciprocal Rank Fusion with smoothing constant k.

Standard default: k = 60 (Cormack et al., 2009).

Fields

k: usize

Smoothing constant.

Weighted

Weighted linear combination of scores.

One weight per child; weights are normalised at execution time.

Fields

weights: Vec<f64>

Per-child weights (will be normalised to sum to 1.0).

Union

Union with max-score-per-document semantics.
