Searching LKML?

E.g. https://lkml.org/lkml/2018/8/30/877 has a link to https://lkml.org/lkml/2018/9/1/41 (and back).

Now, that's only 2 days, but its different months/weeks/whatwever, and that tends to work very badly with archives of the style you prefer, as all threading is broken every so often.

The above two messages in your preferred archive are
http://lkml.iu.edu/hypermail/linux/kernel/1808.3/04944.html
http://lkml.iu.edu/hypermail/linux/kernel/1809.0/00008.html

Please tell me where the thread-next/thread-prev links for these two messages can be found in that archive, because I can't find them, and it really make the whole thing less appealing.
