       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

       Net::LDAP::Control::Sort - Server Side Sort (SSS) control object

SYNOPSIS

	use Net::LDAP::Control::Sort;
	use Net::LDAP::Constant qw(LDAP_CONTROL_SORTRESULT);

	$sort = Net::LDAP::Control::Sort->new(
	  order => "cn -phone"
	);

	$mesg = $ldap->search( @args, control => [ $sort ]);

	($resp) = $mesg->control( LDAP_CONTROL_SORTRESULT );

	print "Results are sorted
"  if $resp and !$resp->result;

DESCRIPTION

       "Net::LDAP::Control::Sort" is a sub-class of Net::LDAP::Control.  It provides a class for manipulating the LDAP Server Side Sort (SSS)
       request control 1.2.840.113556.1.4.473 as defined in RFC-2891

       If the server supports sorting, then the response from a search operation will include a sort result control. This control is handled by
       Net::LDAP::Control::SortResult.

CONSTRUCTOR ARGUMENTS

       order
	   A string which defines how entries may be sorted. It consists of multiple directives, separated by whitespace. Each directive describes
	   how to sort entries using a single attribute. If two entries have identical attributes, then the next directive in the list is used.

	   Each directive specifies a sorting order as follows

	     -attributeType:orderingRule

	   The leading "-" is optional, and if present indicates that the sorting order should be reversed. "attributeType" is the attribute name
	   to sort by. "orderingRule" is optional and indicates the rule to use for the sort and should be valid for the given "attributeType".

	   Any one attributeType should only appear once in the sorting list.

	   Examples

	     "cn"	  sort by cn using the default ordering rule for the cn attribute
	     "-cn"	  sort by cn using the reverse of the default ordering rule
	     "age cn"	  sort by age first, then by cn using the default ordering rules
	     "cn:1.2.3.4" sort by cn using the ordering rule defined as 1.2.3.4

METHODS

       As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the
       current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.
