Struct VectorExclusionOperator 

pub struct VectorExclusionOperator {
    pub positive: Arc<dyn Operator>,
    pub negative_op: VectorSimilarityOperator,
}

VE(V1, V2) = V1 AND NOT V2 — keeps documents from positive that are dissimilar to negative_op’s query. The negative side is wired through a VectorSimilarityOperator threshold so the caller decides what counts as “too similar”.

Fields

positive: Arc<dyn Operator>

negative_op: VectorSimilarityOperator

Implementations
