A pair of candidate scoring functions is chosen from the one or more pairs of candidate scoring functions based on the diversity scores, and the alpha function is selected as the first scoring function and the beta function is selected as the second scoring function. The plurality of search results are presented in an order according to scores from the first scoring function and are presented in an order according to scores from the second scoring function.
