How to use PHP combined with Xunsearch to implement related search and similar recommendation functions

Introduction:
In today’s Internet era, users’ demand for information is getting higher and higher, and search engines have become the first choice for users to obtain information. main ways. In search engines, related search and similar recommendation functions can help users find the information they need more quickly. This article will introduce how to use PHP combined with Xunsearch to implement related search and similar recommendation functions, and give code examples for readers' reference.

1. Introduction to Xunsearch
Xunsearch is a full-text search engine developed based on C, which is efficient and easy to use. It supports Chinese word segmentation, Chinese pinyin retrieval, synonym retrieval and other functions, and is very suitable for related searches and similar recommendations.

2. Implementation of related search function
The implementation of related search function mainly relies on the search interface of Xunsearch. The following is a sample code that uses PHP to call the Xunsearch search interface to implement related search functions:

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

$xs = new XS('demo'); // 创建一个搜索对象
$search = $xs->search; // 获取搜索对象

$search->setFuzzy(true); // 开启模糊搜索

$query = '关键词'; // 用户输入的关键词

$search->setQuery($query); // 设置用户查询的关键词

$docs = $search->search(); // 执行搜索

foreach ($docs as $doc) {
   // 处理搜索结果
   echo $doc->title . '<br>';
   echo $doc->content . '<br>';
   echo '<br>';
}
?>

The above code creates a Xunsearch search object, sets relevant parameters, and finally performs the search operation and iteratively processes the search results. This enables relevant search functionality.

3. Implementation of similar recommendation function
The implementation of similar recommendation function is similar to the related search function, and also relies on the search interface of Xunsearch. The following is an example code that uses PHP to call the Xunsearch search interface to implement the similar recommendation function:

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

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

$docId = '1234'; // 用户当前浏览的文档ID

$search->setFuzzy(true);
$search->setQuery($docId);
$search->setLimit(5); // 获取相似推荐的文档数量

$docs = $search->search(); // 执行搜索

foreach ($docs as $doc) {
    // 处理相似推荐的文档
    echo $doc->title . '<br>';
    echo $doc->content . '<br>';
    echo '<br>';
}
?>

The above code achieves this by setting the document ID currently browsed by the user, limiting the number of similarly recommended documents, and finally performing a search operation. Similar recommendation function.

4. Summary
By combining Xunsearch’s search interface and PHP’s programming capabilities, we can easily implement related search and similar recommendation functions. Related search and similar recommendation functions can greatly improve users' search experience and help users find the information they need more quickly. I hope that the content introduced in this article can be helpful to readers, and interested readers can further study and apply it.
