Find FILTERDEF - inverse not possible?

Trying to invert a Find FILTERDEF in a button to show all images that are not square, is this possible ? The following do not work:

Find FILTERDEF image nomatch aspectratio = 1.0

Find FILTERDEF image match aspectratio != 1.0

Find FILTERDEF image match aspectratio ~ 1.0

image nomatch aspectratio = 1.0 should work. Does the query work if you build it through the UI and run it manually?

It produces the same results - which does exclude the square images but shows all folders and additional files that are not images as well.

type match group Images and image nomatch aspectratio = 1.0
