$index->fields('id');
$index->fields('id', 'name');
$index->fields( 'id, name' );
$index->fields( [ 'id', 'name' ] );
$index->fields( qw[ id name ] );
$index->fields(id => { name => 'name', order_by => 'ASC NULLS LAST' });
my @fields = $index->fields;is_valid

my $isIdentical = $index1->equals( $index2 );AUTHOR
