Craig,
In Word 2002/2003 there is a button on your standard toolbar, number five
from the left, which will activate a taskpane and let you search by creation
date. You can also activate the taskpane directly of course.
Right at the top there is a list op properties, click on it and choose
creation date, choose the second list and click on any condition be it
today, last month or others. Hit the button add. You can of course limit
your search to selected locations or file types.
Now click on search and see what comes up.
