原来是搜索的服务没有安装，

    [iq addAttributeWithName:@"to"stringValue:@"search.localhost"];

I am creating a XMPP sample on ios. What I am trying to do is search user over xmpp. I checked the opernfire server and it has the search plugin enabled. I gone through  and found the stanza. I also gone through  but did

I am done with xmpp connection and login. Now here are the details regarding to my server:

Host Name = 10.x.x.x; Server name = abcd;

The request format I got from the XEP 0055 link is:

    
     
      
       Capulet
      
     
    

I don't know what characters.shakespeare.lit is. I assume this is the server name. So I created following request:

    
     
      
       kapil
      
     
    

but I am not getting any response. I tried to replace the to value with following search.abcd and10.x.x.x but I am not even receiving any response IQ for this rquest.
