[EP-tech] Search API and name fields (or compound)

Hi,

I am trying to write a script to do a search on a dataset.
I would like to find entries where the author field has not been set.

I tried :

   $search->add_field(
      fields => $dataset->get_field('author'),
      match => 'EX',
      value => {family=>'', given=>''}
   );

and

   $search->add_field(
      fields => $dataset->get_field('author'),
      match => 'EX',
      value => {family=>'NULL', given=>'NULL'}
   );
but neither work (they find nothing although there are database entries with both author_family and author_given null). 

Could anybody tell me how I should write the condition ?

Thanks,
GF
