[DXBase] Finding "Confirmed" entered certain days

[Raymond W Brann]

Hi, can't seem to remember how to find Countries Confirmed in a certain 
time span.
Got a new batch of cards from the buro, didn't think was any "new ones" 
and didn't pay
much attention loggin them in.
Now discover I picked up a couple new one's and  like to know which one's.

I remember there is a way to design a search for them and have tried 
with no success.
Any info please.
Thanks
Ray
