If you have a very large number of messages then you will need to add:
# default of 10000 is too small for SEARCH results
imaplib._MAXLINE = 200000
If you want to use the MOVE command you will need this:
# MOVE is not available by default
imaplib.Commands['MOVE'] = ('SELECTED',)
As DL said you need to print out what you get back from the search() and check
that it is what you expect.
