Lucy::Search::SortSpec - Specify a custom sort order for search results.

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

By default, searches return results in order of relevance; SortSpec allows you to indicate an alternate order via an array of SortRules.
Fields you wish to sort against must be sortable.
For a stable sort (important when paging through results), add a sort-by-doc rule as the last SortRule.

my $sort_spec = Lucy::Search::SortSpec->new( rules => \@rules );

Lucy::Search::SortSpec isa Lucy::Object::Obj.
