Using IF statements when the conditions contain complex characters such as >,<,+,=, or "

I have a list of notes for our accounts that contain proprietary code. I have exported these notes to excel and I want to find all the accounts that have the specific line of code below.

<font size="+.25"><font color="blue"><b> Received %50 Down</b></font>

Part of the problem is that the cells may contain other information. I want to use an if statement to return a 1 if the code is in the cell and 0 otherwise. I tried using a wildcard but I think the " and >< characters are messing it up. See the attached file, I need a solution!

=IF(D2="*<font size="+.25"><font color="blue"><b> Received %50 Down</b></font>*",1,0)
Did NOT work

Thanks
