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.

- 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.
