NAME

6       Lucy::Search::SortRule - Element of a SortSpec.
7

SYNOPSIS

9           my $sort_spec = Lucy::Search::SortSpec->new(
10               rules => [
11                   Lucy::Search::SortRule->new( field => 'date' ),
12                   Lucy::Search::SortRule->new( type  => 'doc_id' ),
13               ],
14           );
15

DESCRIPTION

17       SortRules are the building blocks used to assemble SortSpecs; each
18       SortRule defines a single level of sorting.  For example, sorting first
19       by XcategoryX then by score requires a SortSpec with two SortRule
20       elements.
