KinoSearch::Search::LeUsereContributed Perl DoKinoSearch::Search::LeafQuery(3)

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

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
	   );

       ·   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.

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