Integrating Xunsearch with PHP for Fast and Accurate Search

In today’s information‑overloaded era, efficient and precise search engines are essential; combining the popular server‑side language PHP with the Xunsearch engine offers powerful full‑text search capabilities.

Xunsearch, built on the open‑source Xapian engine, supports fast, stable, multilingual (Chinese/English) search with tokenization and pinyin features, and can be seamlessly integrated into PHP applications.

Step 1 – Install Xunsearch : Download the package from the official website, follow the documentation to install and configure it, and use command‑line tools to create and maintain indexes.

Step 2 – Create an Index : Define the fields you want to index (e.g., title, content) and configure tokenization to improve accuracy. Example code:

<?php
require_once '/path/to/sdk/lib/XS.php';
$xs = new XS('demo'); // index name
$index = $xs->index;
$doc = new XSDocument();
$doc->setFields([
  'title'   => 'Example Title',
  'content' => 'Example Content'
]);
$index->add($doc);
$index->flushIndex();
?>

The code loads the Xunsearch SDK, creates an index object, builds a document with the desired fields, adds it to the index, and flushes the data to disk.

Step 3 – Implement Search Functionality : After the index is ready, create a search object, set query parameters, and retrieve results. Example code:

<?php
require_once '/path/to/sdk/lib/XS.php';
$xs = new XS('demo');
$search = $xs->search;
$search->setFuzzy($search->getDefaultFuzzy());
$search->setQuery('example');
$search->setLimit(10); // number of results
$search->setCutOff(5000); // max result count
$result = $search->search();
foreach ($result as $doc) {
  echo $doc->rank() . ": " . $doc->title . "\n";
}
?>

This snippet initializes the SDK, configures fuzzy matching, defines the query term, limits the result set, executes the search, and iterates over the returned documents to display their rank and title.

Conclusion : By leveraging PHP together with Xunsearch, developers can significantly improve the speed and accuracy of search features in web applications, delivering a better user experience.
