I have been through the help topics, but cannot find how to do this. Grateful for any help, please.
The file window search bar searches keywords by default (unless you have restricted it to file names only via the X button).
To filter for keywords, there are two ways:
1. Use a category filter and there the @Keywords category hierarchy
2. Use a Metadata Value filter and select the Keywords tag. The filter then shows you all keywords uses in the current scope (file window) and you can just click to limit by one or more keywords.
This is the most convenient method.

Thank you Mario. I was looking for "Subject". The setting that works is Files with one or more checked values and invert unchecked.
Adobe named keywords XMP:subject in their XMP standard. And hierarchical keywords HierarchicsalSubject.
Invert was on by accident in my screen shot.
Thank you.
