Groups cannot be searched by their descriptions

For the fields of a group, each dutifully has a static Property listed in GroupTermKeys that we can use to plug a TermRestriction when searching. Each field except 'description'.

Looking at the source it appears that those static Properties are simply PropertyImpl s with a hard-coded string. Extrapolating, it would be nice if something like new PropertyImpl<String>("description", String.class) worked, but it doesn't.

My complaining is documented here:
