       String google = "http://www.google.com/search?q=";

        String search = "stackoverflow daterange:2016-01-01..2016-12-31 "; //using the google search operators (daterange)

        String charset = "UTF-8";

        String news="&tbm=nws";

        String string = google + URLEncoder.encode(search , charset) + news;

        String userAgent = "ExampleBot 1.0 (+http://example.com/bot)"; 

        System.setProperty("http.proxyHost", "192.168.5.1");
        System.setProperty("http.proxyPort", "1080");
        for(int j=0;j<3;j++){
     Document document = Jsoup.connect(string+"&start="+(j+0)*10).userAgent(userAgent). ignoreHttpErrors(true).followRedirects(true).timeout(100000).ignoreContentType(true).get();
    Elements links = document.select( ".r>a");
....}
