대용량 데이터에 대한 검색 요청을 처리하기 위해 PHP Elasticsearch를 최적화하는 방법은 무엇입니까?

$params = []; // 定义一个空数组
foreach($data as $item) {
    $params['body'][] = [
        'index' => [

    'index' => 'your_index_name',
    'body' => [
        'settings' => [
            'number_of_shards' => 5, // 分片数
            'number_of_replicas' => 1, // 副本数
        ]
    ]
];
