Smack (and XMPP) ability to perform batch search and add to roster operations?

Question

In general, does XMPP (and in particular the Smack library and the OpenFire server) support batch search and batch add to roster operations? Cross-posted here: http://community.igniterealtime.org/thread/43615

Answer 1

No. One item at a time. This is clarified in section 2.1.5 RFC 3921bis, which was recently approved:

The <query/> element MUST contain one and only one <item/> element.
