> While it's possible to search for fields that don't exist (you'll get 0 hits),  
> you'll get an exception if you try to sort by a field that has no values. The  
> exception is this:  
>   
> if (termEnum.term() == null) {  
>   throw new RuntimeException ("no terms in field " + field);  
> }  
>   
> I'll attach a change suggested by Yonik Seeley that removes this exception. 
>  
> Also, the if-condition above is incomplete anyway, so currently the exception 
> is not always thrown (as termEnum .term() might well be != null but point to a 
> term in a different field already)
