NAME¶
Lucy::Search::SortSpec - Specify a custom sort order for search results.
SYNOPSIS¶
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,
);
DESCRIPTION¶
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.
