	<h1 id="xssearch-">XSSearch 搜索对象</h1>

<p>通过 <a href="../api/XSSearch.html">XSSearch</a> 对象实现各种搜索相关操作。实现使用过程中并不需要自行创建该对象，
而是直接访问 <a href="../api/XS.html#search">XS::search</a> 即可。</p>

<p>默认情况，搜索对象操作时对于用户输入的参数、搜索结果的输出编码视为默认编码，即 <a href="../api/XS.html#defaultCharset">XS::defaultCharset</a>。
如果您需要指定不同编码，请调用 <a href="../api/XSSearch.html#setCharset">XSSearch::setCharset</a> 进行设置。</p>

<p>关于搜索对象的详细用法剖析请阅读后面的专题。</p>
