NAME

KinoSearch::Search::LeafQuery - Leaf node in a tree created by QueryParser.

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

    package MyQueryParser;
    use base qw( KinoSearch::Search::QueryParser );

    sub expand_leaf {
        my ( $self, $leaf_query ) = @_;
        if ( $leaf_query->get_text =~ /.\*\s*$/ ) {
            return PrefixQuery->new(
                query_string => $leaf_query->get_text,
                field        => $leaf_query->get_field,
            );
        }
        else {
            return $self->SUPER::expand_leaf($leaf_query);
        }
    }

DESCRIPTION

LeafQuery objects serve as leaf nodes in the tree structure generated by QueryParser's tree() method. Ultimately, they must be transformed, typically into either TermQuery or PhraseQuery objects, as attempting to search a LeafQuery causes an error.
