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

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