Message-IDUsing the Registry
The registry knows how to map each
Message-ID to the group it’s
in. This can be leveraged to enhance the “article refer method”,
the thing that tells Gnus how to look up an article given its
Message-ID (see Finding the Parent).
nnregistry refer method does exactly that. It has the
advantage that an article may be found regardless of the group it’s
Message-ID is known to the registry. It can
be enabled by augmenting the start-up file with something along these
;; Keep enough entries to have a good hit rate when referring to an ;; article using the registry. Use long group names so that Gnus ;; knows where the article is. (setq gnus-registry-max-entries 2500) (gnus-registry-initialize) (setq gnus-refer-article-method '(current (nnregistry) (nnweb "gmane" (nnweb-type gmane))))
The example above instructs Gnus to first look up the article in the current group, or, alternatively, using the registry, and finally, if all else fails, using Gmane.
