pub fn combmax<I: Clone + Eq + Hash>(
results_a: &[(I, f32)],

) -> Vec<(I, f32)>Expand description
CombMAX: maximum score across all lists.
Formula: score(d) = max(s_r(d)) for all retrievers r containing d.
Use as a baseline or when you want to favor documents that score highly in at least one retriever.
