Can X1 use an image to search for visually similar images?

Hi

Is it possible to use a given image to search all the images on my PC to find images that are "visually similar" using X1 Search?
(e.g. images of different sizes and different formats)

Background:
I keep failing to find certain images that I know are somewhere on my PC but whose master files are poorly named.

And if not, can anyone suggest a cheap search utility that performs this function?

Thanks

J
