[EP-tech] Searching in EP3.2

[Ian Stuart]

Confused here.... I'm trying to restrict a search, and it's returning 0 
results when it should return 19:

This works:

   my $dsd = $session->get_repository->get_dataset("dark_archive");
   my $searchexp2 = EPrints::Search->new(
                                       satisfy_all => 1,
                                       session     => $session,
                                       dataset     => $dsd,
                                      );    # dark archive
   $searchexp2->add_field($dsd->get_field("special_field"),  'FALSE');
   $searchexp2->add_field($dsd->get_field("special_field2"), '');
   my $results2 = $searchexp2->perform_search;
   my $count = $results2->count;
   print "$count records to check\n";
   foreach my $epid (sort @{$results2->ids})
   {
     my $ep = $dso->dataobj($epid);
     next unless $ep->value("field3") eq 'Foo Bar';
     ## do stuff
   }

... this produces 19 results
(notice the 'next' statement in the foreach loop.... a wasteful way of 
doing things.)

When I try:

   my $dsd = $session->get_repository->get_dataset("dark_archive");
   my $searchexp2 = EPrints::Search->new(
                                       satisfy_all => 1,
                                       session     => $session,
                                       dataset     => $dsd,
                                      );    # dark archive
   $searchexp2->add_field($dsd->get_field("special_field"), 'FALSE');
   $searchexp2->add_field($dsd->get_field("special_field2"), '');
   $searchexp2->add_field($dsd->get_field("field3"), 'Foo bar');
   my $results2 = $searchexp2->perform_search;
   my $count = $results2->count;
   print "$count records to check\n";
   foreach my $epid (sort @{$results2->ids})
   {
     my $ep = $dso->dataobj($epid);
     ## do stuff
   }

... this produces 0 results!

Why?
