NAME
Lucy::Search::LeafQuery - Leaf node in a tree created by QueryParser.
SYNOPSIS
package MyQueryParser;
use base qw( Lucy::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.
