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!
