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
