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

    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);
        }
    }

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.

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

• field - Optional field name.
• text - Raw query text.

Accessor for object's field attribute.

Accessor for object's text attribute.
