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.

CONSTRUCTORS ^

new( [labeled params] )

    my $leaf_query = KinoSearch::Search::LeafQuery->new(
        text  => '"three blind mice"',    # required
        field => 'content',               # default: undef
    );

METHODS ^

get_field()

Accessor for object's field attribute.

get_text()

Accessor for object's text attribute.

INHERITANCE ^

KinoSearch::Search::LeafQuery isa KinoSearch::Search::Query isa KinoSearch::Object::Obj.
