I don't know for sure but my guess is that the problem probably has something to do with the info column being a blob. Might want to change that to TEXT or read through MySQL's documention about the blob type and see if there is a way to look through it using like. Not sure how that data type really works. Maybe someone else can recommend something.

BLOB is for Binary objects so I would recommend changing that column to text.
