Help with IF/OR Formula

Hello,

I need to get a formula where if A1 contains either "1" or "2" then output A1, otherwise output blank.

What I've tried isn't working. Don't laugh, but this is my best stab at it:

=IF(ISNUMBER(SEARCH("1",A1))*OR("2",A1),A1,"")

I'm getting: #VALUE!

What am I doing wrong?
