I need to create a new managed property for a date/time field in a list. Unfortunately, when I try to create a new managed property it will only allow me to select "Text" and "Yes/No". If I cannot setup SharePoint to create such managed properties, how can I achieve that in a search items with a date less than "today" should be discarded? I have system permissions - so I don't think it be a permissions issue.
Thank you for your help.
