How to use PHP and Xunsearch to implement search result recommendations and advertising display

In modern Internet applications, search engines are an essential function. In order to improve the user experience, in addition to displaying search results, it is also necessary to recommend results and display advertisements. This article will introduce how to use PHP and Xunsearch to implement search result recommendations and advertising display, and provide code examples.

  1. Installation and configuration of Xunsearch

Xunsearch is a high-performance full-text search engine that supports Chinese word segmentation, fast search speed and easy to use. First, we need to download and install Xunsearch, and then configure it. For specific installation and configuration procedures, please refer to Xunsearch’s official documentation.

  1. Creating a search engine and indexing

Before starting to use Xunsearch, we need to create a search engine and index the data that needs to be searched. The following is a simple sample code:

<?php
require_once '/path/to/XS.php';
$xs = new XS('demo'); // 创建一个名为demo的搜索引擎实例
$index = $xs->index;
$doc = new XSDocument();

// 批量添加数据,并建立索引
$docs = array(
    array('id' => 1, 'title' => 'PHP开发入门教程', 'content' => '本教程是关于PHP开发的入门指南。'),
    array('id' => 2, 'title' => 'PHP进阶教程', 'content' => '本教程是关于PHP进阶开发的指南。')
);

foreach ($docs as $data) {
    $doc->setFields($data);
    $index->add($doc);
}

$index->flushIndex(); // 建立索引
?>
Copy after login
  1. Implementing the search function

Next, let’s implement the basic search function. After the user enters the keyword, we will call Xunsearch's search interface and display the search results to the user. The following is a simple sample code:

<?php
require_once '/path/to/XS.php';

$keyword = $_GET['keyword']; // 获取用户输入的关键字

$xs = new XS('demo'); // 创建一个名为demo的搜索引擎实例
$search = $xs->search;
$search->setQuery($keyword); // 设置查询条件
$search->setLimit(10); // 设置返回结果的数量

$result = $search->search(); // 执行搜索

// 展示搜索结果
foreach ($result as $doc) {
    echo '<h2>' . $doc->title . '</h2>';
    echo '<p>' . $doc->content . '</p>';
}
?>
Copy after login
  1. Realize search results recommendation

In order to improve the user experience, we can recommend related searches based on the user's search history result. First, we need to record the user's search history and store it in the database or cache. Then, based on the user's search history, we can implement the recommendation function of search results. The following is a simple sample code:

<?php
require_once '/path/to/XS.php';

$userId = $_SESSION['user_id']; // 获取用户ID

// 获取用户的搜索记录
// 这里假设搜索记录保存在数据库的search_logs表中
$historyQuery = "SELECT keyword FROM search_logs WHERE user_id = $userId";
// 这里使用数据库查询来获取用户的搜索记录,可以根据具体情况进行调整

$xs = new XS('demo'); // 创建一个名为demo的搜索引擎实例
$search = $xs->search;

// 设置查询条件,将用户的搜索记录作为关键字进行搜索
$search->setQuery($historyQuery);
$search->setLimit(10); // 设置返回结果的数量

$result = $search->search(); // 执行搜索

// 展示推荐的搜索结果
foreach ($result as $doc) {
    echo '<h2>' . $doc->title . '</h2>';
    echo '<p>' . $doc->content . '</p>';
}
?>
Copy after login
  1. Implementing advertising display

In order to implement the advertising display function, we first need to store advertising data in the database and compare it with Search results are associated. Then, when displaying search results, we can insert ads into the results list. The following is a simple sample code:

<?php
require_once '/path/to/XS.php';

$keyword = $_GET['keyword']; // 获取用户输入的关键字

$xs = new XS('demo'); // 创建一个名为demo的搜索引擎实例
$search = $xs->search;
$search->setQuery($keyword); // 设置查询条件
$search->setLimit(10); // 设置返回结果的数量

$result = $search->search(); // 执行搜索

// 展示搜索结果和广告
foreach ($result as $i => $doc) {
    echo '<h2>' . $doc->title . '</h2>';
    echo '<p>' . $doc->content . '</p>';

    // 在第3个结果位置插入广告
    if ($i == 2) {
        echo '<h2>广告标题</h2>';
        echo '<p>广告内容</p>';
    }
}
?>
Copy after login
