751 For the Date header we have three kinda silly match types: `before',
752 `at' and `after'. I can't really imagine this ever being useful, but,
753 like, it would feel kinda silly not to provide this function. Just in
754 case. You never know. Better safe than sorry. Once burnt, twice
755 shy. Don't judge a book by its cover. Never not have sex on a first
756 date. (I have been told that at least one person, and I quote,
757 \"found this function indispensable\", however.)
759 A more useful match type is `regexp'. With it, you can match the date
760 string using a regular expression. The date is normalized to ISO8601
761 compact format first---`YYYYMMDDTHHMMSS'. If you want to match all
762 articles that have been posted on April 1st in every year, you could
763 use `....0401.........' as a match string, for instance. (Note that
764 the date is kept in its original time zone, so this will match
765 articles that were posted when it was April 1st where the article was
766 posted from. Time zones are such wholesome fun for the whole family,

860 Score all followups to the specified authors.
862 This entry is somewhat special, in that it will match the `From:'
863 header, and affect the score of not only the matching articles, but
864 also all followups to the matching articles. This allows you
865 e.g. increase the score of followups to your own articles, or decrease
866 the score of followups to the articles of some known trouble-maker.
868 (gnus-score-string :tag "Thread"
870 Add a score entry on all articles that are part of a thread.
872 This match key works along the same lines as the `Followup' match key.
873 If you say that you want to score on a (sub-)thread that is started by
874 an article with a `Message-ID' X, then you add a `thread' match. This
875 will add a new `thread' match for each article that has X in its
876 `References' header. (These new `thread' matches will use the
877 `Message-ID's of these matching articles.) This will ensure that you
878 can raise/lower the score of an entire thread, even though some
879 articles in the thread may not have complete `References' headers.
880 Note that using this may lead to undeterministic scores of the
881 articles in the thread.
