        if    ( $query->isa("Lucy::Search::ORQuery") )  { ... }
        elsif ( $query->isa("Lucy::Search::ANDQuery") ) { ... }
        elsif ( $query->isa("Lucy::Search::RequiredOptionalQuery") ) {
            ...
        }
        elsif ( $query->isa("Lucy::Search::NOTQuery") ) { ... }
    }
    else { ... }
}
