Q:Why is the maximum taken to calculate the ranking for a grouping,why not the sum?
A:Well,you can do it either way and both are wrong.If you take the sum,then you get the intersection twice.If you take the max,then you miss the difference.Which one to choose?Suppose somebody comes up with a new search term that is 10% of the original.If you take the max,nothing changes.If you take the sum then the ratings will rise 10%.So taking the sum will be an incentive for some to come up with all kinds of obscure terms for a language.That's why we decided to take the max.
问：为什么用最大值计算一组的排名,而不是用和?
A：嗯,用两种方法都可以做到这一点,但都是错的.如果取和,那么就会得到两个交点.如果取最大值,那么就会错过差值.那么到底选择哪一个呢?这里假设采用一个新的搜索条件,其范围是原来的10％：如果取最大值,变化不大；如果取和,那么比率将上升10％.因此,取和将会使一些人提出一个语言中各种晦涩的词语来.这就是为什么我们决定采取最大值的原因.
