[Orgmode] Searching on items scheduled <today +1w>

[Lindsay Todd]

Folks,

    I would like to extract items that are "NEXT" action todo-items
from my master gtd.org file, for reference in my paper planner, and
make a custom agenda command to repeat this.  Most of what I want to
do is easy with the TODO search.  But I don't really want items that
won't be scheduled by sometime in the next week.  I see that TODO
items without a SCHEDULED keyword will always be selected with
+SCHEDULED<"<today>".  But how do I include items scheduled for the
next week as well?

    What hasn't worked:

          +SCHEDULED<"<today+1w>"      (the documentation suggested
this wouldn't work)
          +SCHEDULED<"<+1w>"              (not sure why I thought this
had a chance)

    What does work:

           +SCHEDULED<"<2008-12-05>"   (but only works today!)

     Did I miss something?
