KinoSearch::Search::NOTQuery - Invert the result set of another Query.
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
my $not_bar_query = KinoSearch::Search::NOTQuery->new( negated_query => $bar_query, ); my $foo_and_not_bar_query = KinoSearch::Search::ANDQuery->new( children => [ $foo_query, $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.
