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

754 Score all followups to the specified authors.
756 This entry is somewhat special, in that it will match the `From:'
757 header, and affect the score of not only the matching articles, but
758 also all followups to the matching articles. This allows you
759 e.g. increase the score of followups to your own articles, or decrease
760 the score of followups to the articles of some known trouble-maker.
762 (gnus-score-string :tag "Thread"
764 Add a score entry on all articles that are part of a thread.
766 This match key works along the same lines as the `Followup' match key.
767 If you say that you want to score on a (sub-)thread that is started by
768 an article with a `Message-ID' X, then you add a `thread' match. This
769 will add a new `thread' match for each article that has X in its
770 `References' header. (These new `thread' matches will use the
771 `Message-ID's of these matching articles.) This will ensure that you
772 can raise/lower the score of an entire thread, even though some
773 articles in the thread may not have complete `References' headers.
774 Note that using this may lead to undeterministic scores of the
775 articles in the thread.
