NAME
Lucy::Search::NoMatchQuery - Query which matches no documents.
DESCRIPTION
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.
CONSTRUCTORS
new
my $no_match_query = Lucy::Search::NoMatchQuery->new;
Constructor. Takes no arguments.
METHODS
make_compiler
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.
