NAME

KinoSearch::Search::PolyQuery - Base class for composite Query objects.

DEPRECATED

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/

SYNOPSIS

    sub walk {
        my $query = shift;
        if ( $query->isa("KinoSearch::Search::PolyQuery") ) {
            if    ( $query->isa("KinoSearch::Search::ORQuery") )  { ... }
            elsif ( $query->isa("KinoSearch::Search::ANDQuery") ) { ... }
            elsif ( $query->isa("KinoSearch::Search::RequiredOptionalQuery") ) {
                ...
            }
            elsif ( $query->isa("KinoSearch::Search::NOTQuery") ) { ... }
        }
        else { ... }
    }

DESCRIPTION
