Integrating Xunsearch Full-Text Search Engine with PHP for a Music Website

What is Xunsearch?

Xunsearch is a C++‑based full‑text search engine that can quickly index and search large text data, supports Chinese segmentation, and offers high speed and accurate results. It can be used as a standalone engine or together with PHP.

Installation of Xunsearch:

First, download the latest Xunsearch package from the official website and follow the documentation to install it on the server. After installation, you can use the Xunsearch API for indexing and searching.

Integrating Xunsearch in PHP:

Assuming the PHP Xunsearch extension is installed, follow these steps:

1. Import the Xunsearch library:

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

2. Create a Xunsearch search object:

$xs = new XS('music'); // music is a custom project name

3. Get the searcher and index objects:

$search = $xs->search;
$musicIndex = $xs->index;

4. Set query parameters and execute the search:

$search->setQuery('歌曲名'); // set keyword
$search->setLimit(10); // limit results
$result = $search->search(); // perform search

5. Process the search results:

foreach ($result as $doc) {
    echo $doc->rank() . ': ' . $doc->title . '
';
}

Indexing Song Data:

After integrating Xunsearch, index the music database records as follows:

$musicRecordCount = $db->query('SELECT COUNT(*) FROM music')->fetchColumn();
$musicRecords = $db->query('SELECT * FROM music');

$index = $xs->index;
$index->beginRebuild();

for ($i = 0; $i < $musicRecordCount; $i++) {
    $music = $musicRecords[$i];
    $doc = new XSDocument;
    $doc->setFields([
        'id' => $music['id'],
        'title' => $music['title'],
        'artist' => $music['artist'],
        // other fields
    ]);
    $index->add($doc);
}
$index->endRebuild(); // finish rebuilding

Conclusion

Using PHP together with Xunsearch greatly improves the song search performance of a music website. Xunsearch’s powerful search capabilities and fast response help users quickly find the songs they want, and further optimization can enhance accuracy and speed.
