我刚开始学习这个 出现问题 希望各位大侠能帮忙 急

require("./coreseek/api/sphinxapi.php");
$c1 = new SphinxClient();
$c1->SetServer('localhost',9312);
$c1->SetArrayResult(true);
$c1->SetIDRange(3,4);
$c1->SetFilterRange('id',array(2));
$c1->SetFilterRange('id2',1,3);
$c1->SetLimits(0,20);
$res = $c1->Query('搜索字符串',"*");
echo '<pre>';
print_r($res['bookname']);
print_r($res);
echo '</pre>';


调试结果出现这也的错误[imgs=/forum/img/p.gif][/imgs]Warning: Missing argument 3 for SphinxClient::SetFilterRange(), called in E:\Program Files\AppServ\www\etc\file.php on line 13 and defined in E:\Program Files\AppServ\www\etc\coreseek\api\sphinxapi.php on line 824

$c1->SetFilterRange('id',array(2));

能仔细看看手册么？
你从哪里学的这个用法？
