Question

我正在调试我的提升算法，我无法对调试文本进行调整。问题是以下文字：

358.5638 = product（const（1.0E10），div（int（ViewCount）= 47092，ms（const（1313350611991），str（UploadDate）= 2008-09-19T16：30：16Z）））

现在，如果我的数学运算正确，我们得到1e10 * 47092 / ms（NOW，''that_date''）= 1e10 * 47092 / 9.1510096E10 = 5146.09885。

更糟糕的是，似乎没有一种模式。在此示例的结果的调试信息中，solr计算314.40195，而我计算33667.1973。所以从我的角度来看，solr将这两个结果反过来了！

我是否感到困惑？

感兴趣的读者：这是上述两个示例的调试信息。但是我只对每个条目底部的小FunctionQuery部分感兴趣。

Answer 1

你能解释为什么在

中有str功能

MS（常量（1313350611991），的 STR （UploadDate）= 2008-09-19T16：30：16Z）。））

我假设uploadDate的数据类型是TrieDateField。

如何使用
之类的东西
MS（NOW，uploadDate）
