How to fetch already read articles into summary buffer in gnus?

Question

While in summary buffer how can I make gnus fetching already read articles in two situations:

1. while in a thread with some articles already read (and thus not visible). I would like to complete the thread with all the articles (not only parents!) read or unread.

2. fetch last N read articles which are not visible.

Thanks a ton!

Answer 1

In the summary buffer, to fetch the parent, use ^ (gnus-summary-refer-parent-article) (also available as <menu-bar> <Article> <Fetch parent of article>).

To fetch the whole thread (at least the part that's still on your server), use A T (gnus-summary-refer-thread) (<menu-bar> <Article> <Fetch current thread>).

To fetch more articles, use / o (gnus-summary-insert-old-articles) (also available as <menu-bar> <Gnus> <See old articles>).

Answer 2

For the first question, try

(setq gnus-fetch-old-headers 'some) 

in your .gnus

for the second, when you select the group, it should ask you how many old articles you want to fetch. Does that not work?
