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.

CONSTRUCTORS
   new( [labeled params] )
           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,
           );
