the class SearchPlugin method handleIQRequest.

	 * Handles IQ requests. This method throws an IllegalArgumentException if an IQ stanza is supplied that is not a request (if the stanza
	 * is not of type 'get' or 'set'). This method will either throw an Exception, or return a non-null IQ stanza of type 'error' or
	 * 'result', as XMPP Core specifies that <strong>all</strong> IQ request stanza's (type 'get' or 'set') MUST be replied to.
	 * 
	 * @param iq
	 *            The IQ stanza that forms the request.
	 * @return The response to the request.
