Use PHP and Xunsearch to optimize the keyword search experience of news websites

With the advent of the information age, news websites have become one of the important channels for people to obtain information. However, with the explosive growth of news content, how to efficiently find the content we are interested in from massive news has become a major problem facing search engines. This article will introduce how to use PHP and Xunsearch search engine to optimize the keyword search experience of news websites.

First, we need to install the Xunsearch search engine. Xunsearch is a full-text search engine developed based on PHP. It has the characteristics of fast speed, good search effect, and supports Chinese word segmentation. You can download and install Xunsearch by visiting the Xunsearch official website (www.xunsearch.com).

After the installation is complete, we need to create a Xunsearch index and import the website’s news data into the index. Below is a sample code for creating a Xunsearch index and importing news data into the index.

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();

In the search function of the website, we can use the Xunsearch search engine to provide efficient keyword search functions.

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

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

$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>';
    echo '<br>';
}

In the above code example, we first introduce the Xunsearch SDK and create a Xunsearch search object. Then, we set the search keywords through the setQuery method, and set the number of search results returned through the setLimit method. The addWeight method can set the weight of different fields to match keywords more accurately. Finally, perform the search through the search method and obtain the search results.

At the same time, we can also use the functions provided by Xunsearch to optimize the search experience, such as automatic error correction, search suggestions, search result paging, etc. For specific usage, please refer to Xunsearch official documentation.

Summary:
Using PHP and Xunsearch search engine can effectively optimize the keyword search experience of news websites. By creating indexes and importing data, we can take advantage of the efficient and accurate search capabilities provided by Xunsearch to provide better search results. At the same time, the user experience can be further improved through other functions provided by Xunsearch, such as automatic error correction and search suggestions. I hope this article can be of some help to everyone in optimizing the keyword search experience on news websites.
