Lucy::Search::MatchAllQuery - Query which matches all documents.
MatchAllQuery is a utility class which matches all documents. Each match is assigned a score of 0.0, so that in composite queries, any document which matches against another part of the query will be ranked higher than a document which matches only via the MatchAllQuery.
my $match_all_query = Lucy::Search::MatchAllQuery->new;
Constructor. Takes no arguments.
my $compiler = $match_all_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.
Lucy::Search::MatchAllQuery isa Lucy::Search::Query isa Clownfish::Obj.
