it.unimi.dsi.mg4j.search.score.LinearAggregator

An aggregator that computes a linear combination of the component scorers.

This class requires, beside the usually array of scorers, a parallel array of weights (not to be confused with {@link it.unimi.dsi.mg4j.search.score.Scorer#setWeights(Reference2DoubleMap) index weights}). The score from each scorer will be multiplied by the respective weight, and the overal score will be the sum of these values. Equalisation, if necessary, if performed by maximising over the sample scores and dividing all scores by the resulting value.

      else this.scorer = new LinearAggregator( scorer, weight );
