=head1 NAME

Koha::SearchEngine::Zebra::Search - Search implementation for Zebra

=head1 METHODS

=head2 search

=cut

sub search {
    my ($self,$query_string) = @_;

     my $query = Data::SearchEngine::Query->new(
       count => 10,
       page => 1,
       query => $query_string,
     );

    my $results = $self->searchengine->search($query);

    foreach my $item (@{ $results->items }) {
        my $title = $item->get_value('ste_title');
        #utf8::encode($title);
        print "$title\n";
    }
}

=head2 search_compat

This passes straight through to C4::Search::getRecords.

=cut

sub search_compat {
    shift;    # get rid of $self

    my ( $error, $results_hashref, $facets ) = C4::Search::getRecords(@_);
    if ( C4::Context->interface eq 'opac' ) {
        my $rules = C4::Context->yaml_preference('OpacHiddenItems');
        $facets = Koha::SearchEngine::Search->post_filter_opac_facets( { facets => $facets, rules => $rules } );
    }
    return ( $error, $results_hashref, $facets );
}

=head2 simple_search_compat

This passes straight through to C4::Search::SimpleSearch.

=cut


sub simple_search_compat {
    shift;
    return C4::Search::SimpleSearch(@_);
}

=head2 extract_biblionumber

    my $biblionumber = $searcher->extract_biblionumber( $searchresult );

$searchresult comes from simple_search_compat.

Returns the biblionumber from the search result record.

=cut

sub extract_biblionumber {
    my ( $self, $searchresultrecord ) = @_;
    my $record = C4::Search::new_record_from_zebra( 'biblioserver', $searchresultrecord );
    return Koha::SearchEngine::Search::extract_biblionumber( $record );
}

=head2 search_auth_compat

This passes the search query on to C4::AuthoritiesMarc::SearchAuthorities

=cut

sub search_auth_compat {
    my ( $self, $q, $startfrom, $resperpage, $skipmetadata ) = @_;

    my @params = (
        @{$q}{ 'marclist', 'and_or', 'excluding', 'operator', 'value' },
        $startfrom - 1,
        $resperpage, @{$q}{ 'authtypecode', 'orderby' }, $skipmetadata
    );
    C4::AuthoritiesMarc::SearchAuthorities(@params);
}

=head2 max_result_window

Returns the maximum number of results that can be fetched

Zebra does not have such a limit, so it always returns undef

=cut

sub max_result_window { undef }

1;
