SYNOPSIS

my $sort_spec = Lucy::Search::SortSpec->new(
rules => [
Lucy::Search::SortRule->new( field => 'date' ),
Lucy::Search::SortRule->new( type => 'doc_id' ),
],
);

DESCRIPTION

SortRules are the building blocks used to assemble SortSpecs; each SortRule defines a single level of sorting. For example, sorting first by ``category'' then by score requires a SortSpec with two SortRule elements.

CONSTRUCTORS

    my $by_title   = Lucy::Search::SortRule->new( field => 'title' );
    my $by_score   = Lucy::Search::SortRule->new( type  => 'score' );
    my $by_doc_id  = Lucy::Search::SortRule->new( type  => 'doc_id' );
    my $reverse_date = Lucy::Search::SortRule->new(
        field   => 'date',
        reverse => 1,
    );
