Advanced Search by modify time and sort by date not working

Searching the list archives for "compressed protocol" with the
simple search returns the following recent message, among others:

http://archives.postgresql.org/pgsql-general/2006-09/msg00095.php

Using Advanced Search with "For files modified" set to a value other
than "anytime" doesn't return this message.  Also, although an
"anytime" search does return this message, sorting by date puts it
and a few others from 2006 on the last page.  Other messages on the
third and fourth of the four pages are also out of order when sorted
by date.
