is it possible to do searches based on file size

hi,

is it possible to do searches based on file size. Lets say i want to look for files less than 400mb, is there an easy way to do it?

I tried searching via resolutions such as 768x432 or 720x540 but that doesn't really help. Big files over 1 gig still come through.

thanks in advance

Sorry but this is not possible
