    <input type="text" name="q" id="q" value="{$q}" placeholder="Please enter keywords..." />
    <input type="submit" value="Search" />
</form>

$where = "arc.typeid={$typeid}";

$order = "pubdate DESC";
$pagesize = 10;
$PageNo = isset($PageNo) ? $PageNo : 1;
$PageCount = ceil($totalresult/$pagesize);

$arc = new Archives();
$dsql->SetQuery("SELECT * FROM `#@__archives` WHERE $where ORDER BY $order LIMIT " . ($PageNo - 1) * $pagesize . ", $pagesize");
$dsql->Execute();

while ($row = $dsql->GetObject()) {
