Note that MD5 is slow and CPU-intensive. By design.
If you want a quick way to find matching records then you might find something
like CRC to be more useful. With MD5 it's supposed to be hard for someone to
come up with inputs that hash to a target value, but if you're not too worried
about people trying to do that then MD5 is probably overkill.
