phpinfo里已经有了

scws<br /><br />SCWS support	Enabled<br />SCWS Description	Simple Chinese Words Segmentation<br />PECL Module version	0.2.2<br />SCWS Library	1.2.2<br />SCWS BugReport	http://www.xunsearch.com/scws

但是如下的代码

<br /><?<br />$str="考试前20分钟，凭准考证和身份证进入考场，对号入座，并将准考证、身份证放在桌面右上角";<br />$so = scws_new();<br />$so->send_text($str);<br />$temp=$so->get_result();<br />$so->close();<br />print_r($temp);<br />?><br />

只能产生如下的结果

<br /><br />Array<br />(<br />    [0] => Array<br />        (<br />            [word] => 考<br />            [off] => 0<br />            [len] => 3<br />            [idf] => 0<br />            [attr]

我是按照官方的文档安装的。难道是还需要额外的配置吗？
------解决思路----------------------
字典路径没有配置好吧？
或者是字符集不对
