Finding images without subordinate keywords

[MiamiGringo]

I was wondering if there was a way to filter images that have been assigned a keyword, but have no subordinate keywords. For example, if I have assigned the keyword "Plants" but have not assigned a keyword for the name of the plant species.

Thanks!

I just recently wrote a Tip for this exact purpose! See: Finding images containing only given keyword(s)
