global find on message-id

global find on message-id

[Max Froumentin]

It seems that this feature doesn't already exist but I might be wrong.
I would like to be able to find an article by message-id in all my
mail groups. Exactly like gnus-summary-goto-article, but on all
groups. 

BTW, a bug: when I do gnus-summary-goto-article and look for a non
existing message-id, the message I either get "Couldn't go to article
0", or "gnus-request-article: Wrong type argument: stringp,
nil". Unfortunately I haven't yet been able to find more clues on this.

I use Oort gnus from Jan 1.

Max.

There is no predefined function.

Could you please post the backtraces of the errors?

There is nnir.el which allows you to do this.  But it was written for
other purposes.  It indexes your mail using a search engine and then
allows you to query that index.

The "Required Back End Functions" node of the manual says:
`(nnchoke-request-article ARTICLE &optional GROUP SERVER TO-BUFFER)'
...
     If it is at all possible, this function should return a cons cell
     where the `car' is the group name the article was fetched from,
     and the `cdr' is the article number.  This will enable Gnus to
     find out what the real group and article numbers are when fetching
     articles by `Message-ID'.

I interpreted this to mean that the backend is supposed to search all
groups if the Message-ID isn't found in the given group, so that's
what nnmaildir does.  [^] in the *Summary* buffer and [C-c ^] in the
*Article* buffer will find messages in other groups.  Doesn't this
work with other mail backends?
