I am trying to configure the form for the PreferencesPlugin used for WebPreferences and I find no way to set a variable to an empty string.When I clear a text field this is interpreted as 'do not change' by the PreferencesPlugin. There is also no way to use a special word like none as for the TopicParent. This would be needed for NOSEARCHALL for instance which has to be set to an empty string to disable it.

PreferencesPlugin should be extended in a way to support this. The best I can see is a field attribute ( E for instance) that would allow saving empty values (as opposed to the M attribute).
