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.
