redis添加数据不是加在原数据的后面？

Question

这是redis中原有的数据：

 1) "url:/doi/10.1002/anie.201601258/full"
 2) "url:/doi/10.1002/anie.201601883/full"
 3) "url:/doi/10.1002/anie.201600911/full"
 4) "url:/doi/10.1002/anie.201509978/full"

Redis.set了三条数据，如下：

但是穿插在里面，为什么？
刚学redis，请教。

L'ensemble n'est pas ordonné par définition. Quelle que soit la façon dont le programme est enregistré, vous ne devez pas croire qu'il peut vous donner l'ordre d'origine. Si vous souhaitez commander, utilisez List.
