Smart folder filter "does not contain" Smart Folder Exclude Folder

Ultimately I want the result of this find command to be a smart folder.

The criteria aren't that complicated:


name should be "README.md"
type should be file
path should not contain "node_modules"


find /Users/me/Documents -type f -name README.md -not -path "*/node_modules/*"

The problem is that the smart folders criteria operator list seems to be lacking a does not contain option.

The available options are:


matches
contains
begins with
ends with
is
is not


Is it possible to accomplish this and if so then how?

Edit 1

I found that by holding the option key I am able to add a negation clause to the smart folder search criteria but I cannot seem to successfully exclude the node_modules folder. It is unclear which criteria to use but none of the ones I have tried seem to work:


Document Container
Containing Folder Names
Folder Name


I have tried combining these with the following operators:


contains
matches


and with the following terms:


node_modules
node_modules


in case it supports wildcard searches.

I have tried all combinations of the above filters, operators and terms.

The documentation is so poor on the subject.
It looks like kMDItemPath can't do what you need:
