Wouldn't it be cool if one of the search options was 'file size'?

I would love to be able to search for files named "so and so" greater than 1mb, for example.
One of the reasons for this, is that the Limewire/Frostwire network currently is overflowing with virus's which deceptivly are being named after all the most popular files on the network. And a common denominator for these virus's is that they have a filesize of 851.7kb (check it out!).
