注意您调整阈值时出现的地理图案。
Notice the geographic patterns that appear as you adjust the threshold.
有很多，不过有一条似乎合理的规则是基于这样一种思想，即权系数和阈值的调整应该由分式(t - y)确定。
There are many, but one plausible rule is based on the idea that weight and threshold modification should be determined by a fraction of (t - y).
如果阈值后排序率很高，您就应该增加排序堆阈值(sheapthres)，或通过修改SQL查询调整应用程序以使用较少或较小的排序。
If the value of Post threshold sorts ratio is high, you should either increase the sort heap threshold (sheapthres), or adjust applications to use fewer or smaller sorts via SQL query changes.
