        var options = new GsearcherOptions();
        options.setExpandMode(GSearchControl.EXPAND_MODE_OPEN);

        // 添加了一个网页搜索
        searchControl.addSearcher(new GwebSearch(), options);

        // 搜索结果输出选项，列表显示 GSearchControl.DRAW_MODE_TABED是另外一个选项，tab方式显示各种搜索结果
        var drawOptions = new GdrawOptions();
        drawOptions.setDrawMode(GSearchControl.DRAW_MODE_LINEAR);

        // 每次显示8条搜索结果
        searchControl.setResultSetSize(GSearch.LARGE_RESULTSET);
        // Tell the searcher to draw itself and tell it where to attach
        searchControl.draw(document.getElementById("searchcontrol"), drawOptions);

        // 开始搜索
        searchControl.execute("Google");
