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

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