NAME

Lucy::Search::SortRule - Element of a SortSpec.

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.
