When I create a query and specify sort on a field (the most common is date), the search return set will eliminate hits that do not have a date property set. 

For example, list a set of ancestors with a given surname, then sort by death date.  If the death date was left unspecified, then that hit will not appear. 

My solution was to create a bogus high values date, so that all hits would be returned.

Is there another solution?
