Lucy::Search::NoMatchQuery - Query which matches no documents.
NoMatchQuery is a utility class representing a query which matches nothing. Typical usage might include e.g. returning a NoMatchQuery when a QueryParser is asked to parse an empty string.
my $no_match_query = Lucy::Search::NoMatchQuery->new;
Constructor. Takes no arguments.
my $compiler = $no_match_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.
