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.

CONSTRUCTORS
   new( [labeled params] )
           my $leaf_query = Lucy::Search::LeafQuery->new(
               text  => '"three blind mice"',    # required
               field => 'content',               # default: undef
           );

       ·   field - Optional field name.

       ·   text - Raw query text.

METHODS
   get_field()
       Accessor for object's "field" attribute.

   get_text()
       Accessor for object's "text" attribute.
