Search Shared Items

[uxbod]

I have the following PHP code which works fine to search for contacts within a users personal address book but how would one include any shared items ?

        $request = array(
                "Header" => array(
                        "context" => array(
                                "_jsns" => "urn:zimbra",
                                "authToken" => array(
                                        "_content" => $authToken,
                                ),
                        ),
                ),
                "Body" => array(
                        "SearchRequest" => array(
                                "_jsns" => "urn:zimbraMail",
                                "types" => array(
                                        "_content" => "contact",
                                ),
                                "query" => array(
                                        "_content" => "12345",
                                ),
                        ),
                ),
        );
