KinoSearch::Search::NOTQuery - Invert the result set of another Query.
my $not_bar_query = KinoSearch::Search::NOTQuery->new( negated_query => $bar_query, ); my $foo_and_not_bar_query = KinoSearch::Search::ANDQuery->new; $foo_and_not_bar_query->add_child($foo_query); $foo_and_not_bar_query->add_child($not_bar_query); my $hits = $searcher->hits( query => $foo_and_not_bar_query ); ...
A NOTQuery wraps another Query and matches against its inverse document set. All matching docs recieve a score of 0.0.
NOTQuery is often used in conjunction with ANDQuery to provide "a AND NOT b" semantics.
my $not_query = KinoSearch::Search::NOTQuery->new( negated_query => $query, );
negated_query - The Query whose result set should be inverted.
Accessor for the object's negated query.
Setter for the object's negated query.
