Struct MMRConfig 

pub struct MMRConfig {
    pub lambda: f32,
    pub metric: DistanceMetric,
    pub fetch_multiplier: f32,
}

Configuration for MMR search

Fields

lambda: f32

Lambda parameter: balance between relevance (1.0) and diversity (0.0)

• λ = 1.0: Pure relevance (standard similarity search)
• λ = 0.5: Equal balance
• λ = 0.0: Pure diversity

metric: DistanceMetric

Distance metric for similarity computation

fetch_multiplier: f32

Fetch multiplier for initial candidates (fetch k * multiplier results)
