I doubt a school would search every applicant just to see what would come
up, but I wouldn't put it past an interviewer if they have your file beforehand or other faculty/staff that might review files.
I won't give details of the story since I don't have his permission, but I recently heard a classmate's story from one of his interviews. The interviewer saw something interesting in his statement/application and did some searching. He pulled it up during the interview. It wasn't a terrible thing and he still got accepted at that school, but it certainly was not something he expected to face in his interview.
