//拆词
//SPH_MATCH_ALL 和 SPH_MATCH_ANY 的区别：
//搜索“LAMP兄弟连”，ALL的结果：完整包含“LAMP兄弟连”才能被搜出来，
//单纯包含“LAMP”或单纯包含“兄弟连”的搜索不出来，没有拆词的功能。
//ANY则可以搜索出来拆开后的词的结果。此处使用ANY
$sphinx->SetMatchMode(SPH_MATCH_ANY);
//通过query方法搜索,“*”表示在所有的索引中搜索，相当于命令行里面的“./indexer --all”
$result=$sphinx->query("$keyword","documents,delta");
//打印搜索的结果
echo "<pre>";
print_r($result);
echo "</pre>";

//上面打印的结果中，数组的 [matches]循环便利，下标就是搜索到的文档的主键Id
//使用PHP中的 array_keys()函数即可拿到下标，即：要查找的文档的主键
//print_r(array_keys($result[‘matches‘]));
//结果如下：Array([0]=>1)

//使用implode或者 join用逗号把查询出来的主键连接起来：
if (!isset($result[‘matches‘])) {
    echo "为搜索到结果";
    exit;
}
$ids = join(‘,‘,array_keys($result[‘matches‘]));
