如何使用PHP和Xunsearch进行搜索结果的跟踪和日志分析

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

$xs = new XS('demo'); // demo为我们创建的项目名称
$index = $xs->index;
$index->beginRebuild(); // 开始重建索引

// 添加一些文档到索引中
$doc = new XSDocument;
$doc->setFields([
  'title' => 'example document',
  'content' => 'this is a test document',
  'url' => 'http://example.com'
]);
$index->add($doc);

// 结束重建索引
$index->endRebuild();

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

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

$query = $_GET['q']; // 获取用户的搜索关键词

$docs = $search->setQuery($query)->search(); // 执行搜索

// 输出搜索结果
foreach ($docs as $doc) {
    echo $doc->title . '<br>';
    echo $doc->content . '<br>';
    echo $doc->url . '<br>';
    echo '<br>';
}

// 记录搜索日志
$logger = new XSLog('/path/to/logfile.log');
$logger->log('搜索关键词：' . $query);
$logger->log('搜索结果数量：' . count($docs));
$logger->log('用户IP地址：' . $_SERVER['REMOTE_ADDR']);
$logger->flush();
