*
* <ul>
* <li>XS 是 XunSearch 的统一缩写, XS 是解决方案而不仅仅针对搜索, 还包括索引管理等</li>
* <li>XS 运行环境要求 PHP 5.2.0 及以上版本, 带有 SPL 扩展</li>
* <li>如果您的数据包含 utf-8 以外的编码(如: gbk), 则要求安装 mbstring 或 iconv 以便转换编码</li>
* <li>对于 bool 类型函数/方法若无特别说明, 均表示成功返回 true, 失败返回 false</li>
* <li>对于致命的异常情况均抛出类型为 XSException 的异常, 应将 xs 所有操作放入 try/catch 区块</li>
* <li>这只是 XunSearch 项目客户端的 PHP 实现, 需要配合 xunsearch 服务端协同工作</li>
* </ul>
*
* 用法简例:
* <pre>
* try {
* // 创建 xs 实例 (包含3个字段 id, title, content)
* $xs = new XS('etc/sample.ini');
*
* // 索引管理
* $doc = new XSDocument('gbk');
*
* // 新增/根据主键更新数据
* $doc->id = 123;
* $doc->title = '您好, 世界!';
* $doc->setFields(array('content' => '英文说法是: Hello, the world!'));
* $xs->index->add($doc);
*
* $doc->title = '世界, 你好!';
* $xs->index->update($doc);
*
* $xs->index->del(124); // 删除单条主键为 124 的数据
* $xs->index->del(array(125, 126, 129)); // 批量删除 3条数据
*
* // 正常检索
* // 快速检索取得结果
* // 快速检索匹配数量(估算)
*
* } catch (XSException $e) {
* echo $e . "<br />\n";
* }
* </pre>
