Lucy::Search::ANDQuery - Intersect multiple result sets.
my $foo_and_bar_query = Lucy::Search::ANDQuery->new( children => [ $foo_query, $bar_query ], ); my $hits = $searcher->hits( query => $foo_and_bar_query ); ...
ANDQuery is a composite Query which matches only when all of its children match, so its result set is the intersection of their result sets. Documents which match receive a summed score.
my $foo_and_bar_query = Lucy::Search::ANDQuery->new( children => [ $foo_query, $bar_query ], );
Create a new ANDQuery.
children - An array of child Queries.
my $compiler = $and_query->make_compiler( searcher => $searcher, # required boost => $boost, # required subordinate => $subordinate, # default: false );
Abstract factory method returning a Compiler derived from this Query.
searcher - A Searcher.
boost - A scoring multiplier.
subordinate - Indicates whether the Query is a subquery (as opposed to a top-level query). If false, the implementation must invoke normalize() on the newly minted Compiler object before returning it.
