xmpp/ejabberd用户搜索返回空字段

这是我对运行在本地主机上的ejabberd服务器的查询，使用window telnet搜索用户是否存在

本地服务器主机名为durgesh laptop

服务器响应为：-

<iq from='vjud.durgesh-laptop' to='durgesh@durgesh-laptop/Telnet Client'          id='searchByUserName' type='result'>
<query xmlns='jabber:iq:search'>
<x xmlns='jabber:x:data' type='result'>
<title>Search Results for vjud.durgesh-laptop</title>
<reported><field type='text-single' label='Jabber ID' var='jid'/>
<field type='text-single' label='Full Name' var='fn'/>
<field type='text-single' label='Name' var='first'/>
<field type='text-single' label='Middle Name' var='middle'/>
<field type='text-single' label='Family Name' var='last'/>
<field type='text-single' label='Nickname' var='nick'/>
<field type='text-single' label='Birthday' var='bday'/>
<field type='text-single' label='Country' var='ctry'/>
<field type='text-single' label='City' var='locality'/>
<field type='text-single' label='Email' var='email'/>
<field type='text-single' label='Organization Name' var='orgname'/>
<field type='text-single' label='Organization Unit' var='orgunit'/></reported></x>
</query></iq>

它包含空字段。无论用户是否存在，它总是以空字段值响应 请告诉我哪里做错了
