Search Box + YES/NO Output

Hello Everyone, I need to make my Search Box a bit smarter than it is, I guess there is a solution for this since I have found some functions that by themsleves do part of what I need.

Please look at the Screenshot (Sample workbook attached as well):

• I need to Input a value/string into the Search Box in/over C2
• If the value/string is found in Colum A, then please give the output "OUT", in colum B, if not just stay at "?".
• This output should stay at "OUT" though...because I will input other value/string in the search box.

I would be extremely grateful for some help here.

Thanks a lot and regards,
