PHP와 Manticore Search를 활용한 지식 그래프 검색 기능 개발

<?php
// 知识图谱数据导入示例代码
$host = 'localhost';
$port = 9308;

// 连接Manticore Search
$client = new ManticoresearchClient([
    'host' => $host,
    'port' => $port
]);

// 创建索引
$client->indices()->create([
    'index' => 'movies',
]);

// 定义字段
$fields = [
    'id' => ['type' => 'integer'],
    'name' => ['type' => 'text'],
    'director' => ['type' => 'text'],
    'actor' => ['type' => 'text'],
    'genre' => ['type' => 'text'],
    'rating' => ['type' => 'float'],
];

// 创建文档
$movies = [
    ['id' => 1, 'name' => 'The Shawshank Redemption', 'director' => 'Frank Darabont', 'actor' => 'Tim Robbins, Morgan Freeman', 'genre' => 'Drama', 'rating' => 9.3],
    ['id' => 2, 'name' => 'The Godfather', 'director' => 'Francis Ford Coppola', 'actor' => 'Marlon Brando, Al Pacino', 'genre' => 'Crime', 'rating' => 9.2],
    // 其他电影数据...
];

// 将文档添加到索引中
$documents = [];
foreach ($movies as $movie) {
    $document = new ManticoresearchDocument();
    $document->setIndex('movies');
    $document->setId($movie['id']);
    $document->setFields($movie);
    $documents[] = $document;
}

$client->bulk($documents);

// 关闭连接
$client->getConnection()->close();

<?php
// 电影搜索示例代码
$host = 'localhost';
$port = 9308;

// 连接Manticore Search
$client = new ManticoresearchClient([
    'host' => $host,
    'port' => $port
]);

// 构建查询语句
$query = new ManticoresearchQueryBoolQuery();
$query->addMust(new ManticoresearchQueryMatchQuery('name', 'The Shawshank Redemption'));
$query->addMust(new ManticoresearchQueryMatchQuery('actor', 'Morgan Freeman'));
$query->addMust(new ManticoresearchQueryMatchQuery('director', 'Frank Darabont'));

// 执行查询
$search = new ManticoresearchSearch($client);
$search->addIndex('movies');
$search->setQuery($query);
$result = $search->search();

// 输出结果
print_r($result->getDocuments());

// 关闭连接
