It uses the POSIX regex lib that is included in glibc.

(man 7 regex)

The Expression filter expects the scheme-like filter language that
Evolution uses. For examples, you cn take a look at
/usr/share/evolution/filtertypes.xml

I don't think you can tweak the xml file to add support for this
particular thing (although you can certainly add more functionality by
adding/changing the xml file).

The xml file mostly just contains the basics, you can do more complex
stuff using the Expression language which isn't really documented (yet -
mostly because it changes slightly now and again).

If you want, feel free to add a request to be able to unset a flag
(which is what you want), we currently only support setting a flag.
