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

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