如何在Laravel控制器中查询ElasticSearch

use Elasticsearch\ClientBuilder;

class MyController extends Controller
{
    public function search()
    {
        // 创建Elasticsearch客户端
        $client = ClientBuilder::create()->build();

        // 创建Elasticsearch查询
        $params = [
            'index' => 'my_index',
            'type' => 'my_type',
            'body' => [
                'query' => [
                    'match' => [
                        'field' => 'value'
                    ]
                ]
            ]
        ];

        // 执行查询
        $response = $client->search($params);

        // 处理查询结果
        $hits = $response['hits']['hits'];
        foreach ($hits as $hit) {
            // 处理每个匹配的文档
            $source = $hit['_source'];
            // ...
        }

        // 返回结果
        return response()->json($hits);
    }
}
