@end lisp
By default, threads are sorted recursively, that is, first the roots,
then all subthreads, and so on. If you feel more like sorting only
the roots, so that inside a thread the original chronological order is
retained, you can set @code{gnus-sort-threads-recursively} to nil.
@vindex gnus-thread-score-function
The function in the @code{gnus-thread-score-function} variable (default
@code{+}) is used for calculating the total score of a thread. Useful
