5 years ago 多扫了一些结果，发现几百万的记录中，有f的一共就360+条，而f和s不等的只有20+。另外发现了b和z，在全部记录中也只有大约10条（有b的也有z，有z的也有b）。所以这些f/b/z可能是早期用过的复数/比较级/最高级吧。

要提同样的问题，发现系统提示了这个类似问题，调研了一下，猜测如下：
找出前100个有f的exhcnage字段，发现数量不多，77w+的词条中才有100个，就这100个词条仅比对s和f，发现f和s多数一致，不一致的5个中，有2个只有f没有s，另外3个的f比s准确。所以猜测f是对一些名词复数形式的fix，如果发现了f，可以采用f而弃用s。
待向 @skywind3000 求证。
s和f不一致的几个：
