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

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