In Scrivener, how can I do a "Negative Search"?

Scrivener is a wonderful program!

Is there a way of doing a “Negative Search” in a large Scrivener project?

In a project that has ‘Memory’ as a keyword. I can search for all documents having ‘Memory’ as a keyword. Can I also quickly list all the documents that DO NOT HAVE ‘Memory’ as keyword?

We don’t yet have a good way of doing this, but there are plans to make it possible in the future.
