Names of search service criteria depend on content type that define the model item. If an attribute is overridden in a subtype after the service has been configured, the criterion does not work anymore

How to reproduce:

• Use ODF programItem's orgUnit attribute
• Create a search service on courses with a criterion on orgUnit attribute
• Add an override of course content type to modifiy the orgUnit attribute (make it mandatory by exemple)
• Look at your service's criterion => it is KO
