NAME
Lucy::Search::ORQuery - Union multiple result sets.
SYNOPSIS
my $foo_or_bar_query = Lucy::Search::ORQuery->new(
children => [ $foo_query, $bar_query ],
);
my $hits = $searcher->hits( query => $foo_or_bar_query );
...DESCRIPTION
ORQuery is a composite Query which matches when any of its children match, so its result set is the union of their result sets. Matching documents recieve a summed score from all matching child Queries.
CONSTRUCTORS
new
my $foo_or_bar_query = Lucy::Search::ORQuery->new(
children => [ $foo_query, $bar_query ],
);Create a new ORQuery.
children - An array of child Queries.
METHODS
make_compiler
my $compiler = $or_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.
