Digital BW, The Print

I'm fairly new to the group and have noticed that It seems impossible to actually do a 
Search of the entire Archive for a specific subject.  Seems like it only searches the past 
month or so.  Can anyone give me any pointers as to what I'm doing wrong or if it's just 
not possible.  It's very frustrating as I know many questions I have are most likely 
addressed in the archives somewhere - It's just a matter of finding it.  Thanks very much 
for such a great group.
