Filter the current week in Outlook Calendar with SQL DASL

Hello!

I'm trying to make a new view in Outlook Calendar that displays meetings with a specific subject. The problem is that I can't find anywhere how to show the meetings for the current week only.

My SQL DASL syntax is so far:

"http://schemas.microsoft.com/mapi/proptag/0x0037001f" LIKE '%21%'

And the result is:

I have tried to use the %thisweek% parameter without result as I don't know how this should be used (look here to see what I mean http://blogs.msdn.com/b/andrewdelin/archive/2005/05/11/416312.aspx?Redirected=true).

Thanks in advance!
