Microsoft Outlook: Search for messages with Subject 'Starting with'

I can't figure out how to set up a simple search. I am trying to find all messages that 'start with' a particular string. Here is an example of 4 message

1) Subject: ABC DEF 2) Subject: ABC XYZ 3) Subject: RE: ABC DEF 4) Subject: FW: ABC XYX 

From this list; I only want to search for message 1 and message 2. But for some reason; the advanced find only show me options like

a) contains b) is c) doesn't contain d) word starts with ..... and so on 

but none of those work for me :(

There is no space between NOT and (Subject... ).

the right search is (subject: "ABC ") and NOT(subject: "RE: ") and NOT(subject: "FW: " )

Try this:

subject:abc and subject:def not subject:"re:"
