yaz_sort - Sets sorting criteria

SYNOPSIS

       void yaz_sort (resource	$id, string  $criteria)

DESCRIPTION

	This function sets sorting criteria and enables Z39.50 Sort.

	Call this function beforeyaz_search(3). Using this function alone does not have any effect. When used in conjunction with yaz_search(3), a
       Z39.50 Sort will be sent  after	a  search  response  has  been	received  and  before  any  records  are  retrieved  with  Z39.50  Present
       (yaz_present(3).

PARAMETERS

	      o $id
		- The connection resource returned by yaz_connect(3).

	      o $criteria
		- A string that takes the form field1 flags1 field2 flags2 where field1 specifies the primary attributes for sort, field2 seconds,
		etc..  The field specifies either a numerical attribute combinations consisting of  type=value	pairs  separated  by  comma  (e.g.
		1=4,2=1)  ;  or  the  field  may specify a plain string criteria (e.g.	title. The flags is a sequence of the following characters
		which may not be separated by any white space.

		     Sort Flags

		     o a - Sort ascending

		     o d - Sort descending

		     o i - Case insensitive sorting

		     o s - Case sensitive sorting

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      Sort Criterias

	       To sort on Bib1 attribute title, case insensitive, and ascending you would use the following sort criteria:

	      1=4 ia

	       If the secondary sorting criteria should be author, case sensitive and ascending you would use:

	      1=4 ia 1=1003 sa

NAME

       Sort::Key::Register - tell Sort::Key how to sort new data types.

SYNOPSYS

	 use Sort::Key::Register Person =>
	     sub { $_->surname, $_->name },
	     qw(string string);

	 use Sort::Key::Register 'Color::Component' => 'integer';

	 use Sort::Key::Register Color =>
	     sub { $_->R, $_->G, $_->B },
	     ('Color::Component') x 3;

DESCRIPTION

       Sort::Key::Register allows one to register new data types with Sort::Key so that they can be sorted as natively supported ones.

       It works as a pragma module and doesn't export any function, all its functionality is provided via "use":

	 use Sort::Key::Register ...

       To avoid collisions between modules registering types with the same name, you should qualify them with the package name.

	 use Sort::Key::Register 'MyPkg::foo' => sub { $_ }, '-int';

	 # or using __PACKAGE__:
	 use Sort::Key::Register __PACKAGE__, sub { $_ }, '-int';

   USAGE
       use Sort::Key::Register $name => &multikeygen, @keytypes;
	   registers type $name.

	   &multikeygen is the multikey extraction function for the type and @keytypes are the types of the extracted keys.

       use Sort::Key::Register $name => $keytype;
	   this 'use' is useful for simple types that are sorted as another type already registered, maybe changing the direction of the sort
	   (ascending or descending).
