使用PHP和Xunsearch优化新闻网站的关键词搜索体验

require_once '/path/to/xunsearch/sdk/php/lib/XS.php';

$xs = new XS('news');
$index = $xs->index;

// 创建索引结构
$index->clean();
$newsField = $index->addField('title');
$newsField->setAnalyzer('scws');
$newsField = $index->addField('content');
$newsField->setAnalyzer('scws');

// 导入新闻数据
$news = [
    ['id' => 1, 'title' => '新闻标题1', 'content' => '新闻内容1'],
    ['id' => 2, 'title' => '新闻标题2', 'content' => '新闻内容2'],
    // 更多新闻数据...
];

foreach ($news as $new) {
    $doc = new XSDocument();
    $doc->setField('id', $new['id']);
    $doc->setField('title', $new['title']);
    $doc->setField('content', $new['content']);
    $index->add($doc);
}

$index->flushIndex();

require_once '/path/to/xunsearch/sdk/php/lib/XS.php';

$xs = new XS('news');

$keyword = $_GET['keyword'];

$search->setQuery($keyword);
$search->setLimit(10);

$search->addWeight('title', 10); // 标题的权重更高
$search->setCharset('UTF-8');

$result = $search->search();

foreach ($result as $item) {
    echo '标题：'.$item->title.'<br>';
    echo '内容：'.$item->content.'<br>';
