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