    PositiveScoreImpact

    Rank features that correlate negatively with the score should set PositiveScoreImpact to false (defaults to true). This will be used by the rank_feature query to modify the scoring formula in such a way that the score decreases with the value of the feature instead of increasing. For instance in web search, the url length is a commonly used feature which correlates negatively with scores.

    Declaration
    public bool PositiveScoreImpact { get; set; }
    Property Value
    Type Description
    bool
