XEP-0059: Result Set Management

2. Use Cases

2.1 Limiting the Number of Items

In order to limit the number of items of a result set to be returned, the requesting entity specifies a request type of "set" and the maximum size of the desired subset (via the XML character data of the <max/> element):

Example 1. Requesting a Limit to the Result Set

<iqtype='set'from='stpeter@jabber.org/roundabout'to='users.jabber.org'id='limit1'>
  <queryxmlns='jabber:iq:search'>
    <nick>Pete</nick>
    <setxmlns='http://jabber.org/protocol/rsm'>
      <max>10</max>
    </set>
  </query>
</iq>
    

The responding entity then returns the first items of the result set in order. The number of items is limited to the requested size:

Example 2. Returning a Limited Result Set

<iqtype='result'from='users.jabber.org'to='stpeter@jabber.org/roundabout'id='limit1'>
  <queryxmlns='jabber:iq:search'>
    <itemjid='stpeter@jabber.org'>
      <first>Peter</first>
      <last>Saint-Andre</last>
      <nick>Pete</nick>
    </item>
    .
    [8 more items]
    .
    <itemjid='peterpan@neverland.lit'>
      <first>Peter</first>
      <last>Pan</last>
      <nick>Pete</nick>
    </item>
  </query>
</iq>
